USB write speed w/CM9 - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I am running a nightly build of CM9. I have read the various posts on USB write speeds in the 1MB/s range, which is what i am experiencing as well. I have tried all the rd_ahead tweaks in programs like SD Speed Increase which only helps out minimally. While using SD Speed Test I saw speeds around 7.01MB/s Write, and 15MB/s Read, now I also read about this affecting all .37 kernels? Has this not been fixed yet in any kernel that can be flashed to CM9? 1.2-2MB/s is a far shot away from 6MB/s

I know this isn't the solution you are looking for, but the only workaround I can suggest is a Wifi File Manager app. It seems CM9 is being retired in favor of CM10, so hopefully it will be addressed in CM10, but I don't think it will be fixed in CM9. (I could be wrong)

Thank you for your reply. I did see people discussing WIFI transfers, i will definitely try that as well. For now i just like to boot into recovery and mount the usb storage for large file transfers, wifi would probably be more efficient since it would eliminate a boot.

Rooted Using Kernels from Adrynalyne- Anybody Getting Slow Upload Speeds?

Sorry- I'm new so I can't post in the development section but I'm using the 4.3 versions of Adrynalyne's kernels and I'm getting slower donwload speeds and much slower upload speeds (closer to 500k). When I flashed back to the stock kernel the dl and upl speeds went back to normal. Anybody else getting this?

Kernel has absolutely nothing to do with your network speeds. That was likely a fluke.
Network speeds are affected by a number of things-signal strength and network congestion being the biggest factors.
Do several tests different times of day and you will see that 3g can vary from 30 to 2100 kbps download speeds. As for 4g.. Idk what typical speeds are, but it will have a similar range.
via Incredible Redemption
Thanks AdhvanIt for the response but I tried testing them within minutes of flashing kernels and did numerous tests. With stock kernel I was getting about 8-12mbs donwloads and believe it or not upwards to 25+ mbs uploads (and that's consistently) while with the Adrynalyne's ROMS (using different versions- a-c) I was getting about 3-6 mbs downloads and 1-2 mbs uploads. Granted 3-6 is good enough but the disparity between 3-6 and 8-12 for uploads and 2 and 25 is quite a difference. You mention that kernels have nothing to do with speed but I was wondering if undervolting has any effect on the radio? Is anybody else having donwload/upload issues?
The upload speeds on the speed test app are completely wrong. If anything, the Adrynalyne kernel brought it closer to what it should be. Tether the internet from your phone to your computer, then go to the speed test web site. That'll show you what it should be.
Tried tethering (which always seems slower) and got the same results with the 4.a - 4.3 kernels. If anybody is trying this kernel are you getting the same results? I really love this kernel and Adrynalyn's work is always top notch. I don't know if this is just my phone with maybe a bad radio?
that has to be the kernel.. check for updates... or try somthing different.

I'm all ears on the explanation of why it has to be.
Hi Adrynalyn. First, thanks for all of the work and time you put in. I can't post in the development thread or otherwise I would have posted this thread there. Also, thanks for checking in on the thread. Is it just my experience with the download speed using the 4.3 kernels? Thanks!
Im using his 4.3b and my speeds are fine. All his kernals have done well for me. As stated above 4g speeds should be around 7-12down and 4-6up. At least in NY that is the usual besides some slighty higher numbers once in a while.
I would redownload and try flashing again. Are you using rom manager to flash or going into recovery. I have done both and it seems fine...
Not to jack the thread... but
I am new and can't post in the dev section yet. Adrynalyn, just wanted to express my gratitude for all your hard work!!! Tried a couple other ROM's, but just LOVE yours and came back within minutes of each experience...
In my strongest 4g LTE area I get 15/5 pretty regularly on adryns kernels and from what I understand thats all your really sposed to be seeing...
Thanks to you guys for responding- it looks to be unique to my situation then. I'm flashing via recovery. Would that make a difference? I'm in San Jose and I had been getting incredible upload speeds- frequently hitting above 30mbs. My donwloads have always been lower but flashing with these kernels I haven't been able to duplicate. Maybe it's because I'm using the stock but rooted ROM? Jrocker23- are you using the stock rom, too?
Yes, all I did was root via adb and added Adranalyne's kernals. Im running .06 stock. Also flashing from recovery should work fine. Are you using setcpu or running with the stock kernal speed?

Funny you say this because I am in the San Jose area and before would hit 15-30mbs and now with adryns~ 4.3a kernel I get only 3/1mbs @ speakeasy website. This is rather weird.. Let me try a different kernel and report back with speeds.
Smok3d-
I'm also from the San Jose area. I was getting blazing uploads but now I can't get it over 2mbs. Something to do with our area's towers? Smok3d- could you revert back to the stock kernel? I did and was getting the regular speeds- I wonder if that's it too?
Ok there is definitely an issue going on here with kernels and speeds.
I was using Teslacoil with the included kernel and my speed in 3G area was snappy, when running speed tests I'd consistently get around 1.5 meg.
Yesterday i flashed the latest Virus rom with recommended Ziggy BFS kernel, and i almost automatically noticed my speed was running considerabley slower. When running a speed test, I'd get only around 100 KB down.
So today, i flashed the latest Virus rom again but this time i flashed Imoseyon normal lean kernel on it and now my speeds are back to 1.5 MB.
Now i know that speed tests are not accurate when run from the phone itself, however, the difference in speed is so dramatic that you don't even need to run a speed test to notice it right away.

And what is it with adrynalyne kernel that is the problem? I would love to know. I'm running it and my real speeds are great. You are running speed tests, bet if you didn't you wouldn't even notice the speed. Just because you are getting a certain speed from a TEST doesn't mean you will get the same in real world performance. Do research or provide facts before you make statements you can't back up

L00k above at my post... I automatically noticed my speed was considerably slower before even running a speed test. Then i change kernels, and its magically back to normal.
I'm no dev, so i couldn't begin to explain what in the kernel would cause it. And just because you aren't experiencing the issue doesn't mean it doesn't exist for others. Who knows? Maybe it was just a bad flash or CWR didn't clean cache properly before flashing, anything is possible, but we should work together to bring resolution to issues that arise, even if it is just happening to some...

[Q] Any common tweaks to improve transfer rates to internal storage?

Well, my tf101 is transfering data to the internal storage (/sdcard) at very slow speeds. Antutu is reporting Write speed of 4.5-8MB/s and Reed speeds of 19-22MB/sec.
This seems pretty bad in general, but my Rezound with similar specs is getting ~20MB/sec write speeds and it just says ">50MB/sec" Read speeds and doesn't even bother to give an actual value...
anybody know of any scripts, tweaks, mods, anything to improve the situation?
it is beause of the partitioning in honeycomb. The more data you have the lower the speed you can mess around with system tuner to get a better value though

Can you clarify at all? How does the partitioning differ? I was getting speeds like that on my Rezound when it was running Android 2.3.4 Gingerbread, and now its running 4.0.1 and still getting much faster speeds than my TF. How is the partitioning in Honeycomb somehow affecting the transfer speed if a previous version of Android didn't exhibit this issue?...

Terrible I/O - TF700t

Got it for 4 days now. Terrible speeds when downloading content not because of the WiFi but the storage.
It is very difficult to use any torrent client as the whole tablet stalls. Very difficult to install big games as MC3.
Tried both default and rooted, changed the IO scheduler - no big difference. Copying files from PC takes a LOT of time as well. Seq read 17 MB/s , seq write 4 MB/s ...
The really bad thing is that the whole tablet becomes unusable - even the mouse pointer does not work when there is a long IO operation going on.
Any thoughts since the problem is not solved for the whole Transformer family?

Try plugging a USB disk to your dock or use the SD card. Works faster for me.
Some benchmarks ..

Sent from my ASUS Transformer Pad TF700T using xda premium
I'm getting similar results in the benchmarks mostly, so let's consider it a standard for the Infinity
I would be worried, however, about 0.5 MB/ write speed! If you get it constantly and even with sio scheduler, I would definitely consider having the device replaced on warranty terms. Something like 10x that speed could be considered a (lower end of) standard on TF700.
---------- Post added at 06:44 PM ---------- Previous post was at 06:34 PM ----------
Try different (benchmarking) programs however. Androbench has been said to give false results on some devices.
I've done a simple test using SD Card Tester now (500MB test file), in balanced mode it's somewhere near 8 MB/s write* and 18MB/s read for the internal storage on average, and 5 MB/s W + 17 MB/s R for the microSD card (AFAIR the best results were for the full-size SD card, something about 15/30, but I'm without the dock at the very moment).
Hope this helps.
* it starts with 17, but then decreases because of the numerous lags (happening all the time when writing bigger files on the Infinity, sadly)
---------- Post added at 06:48 PM ---------- Previous post was at 06:44 PM ----------
Ah, and don't compare it to phones
See http://www.androidpolice.com/2012/0...hmark-11-modern-devices-compared-in-13-tests/ as reference point (originally posted by shinzz).
Noticed this major problem as well.
Basically it can be triggered by uploading lots of files using wifi to the tf700 running airdroid. Then using the stock music player it will lag like hell...
Then again, if you run airdroid on another android device and the launch a internet browser (either stock or dolphin) connect to that device running airdroid, basically becomes totally slow but this maybe caused by the browser itself....
Not to mention the kernel constantly clocks the processor in range 100MHz - 500GHz this further, push I/O to even more constrained.
The CPU speeds can be changed by using different CPU governor. In my opinion the default "interactive" governor actually performs pretty well (performance/battery life).
It has been referenced in several other threads that, indeed, the I/O of the TF700T is absolutely abysmal. That 500 kB/s is really, really low, though. I have the lags all the time, and several movies files have stopped playing many times during my (long) commute viewing tries... I really hope that custom ROMs can better this by a fair margin. though I don't know to what extent it has been the case with the Prime's similar issues. Gotta go and nose around in the AndroWook thread a bit...
Full-size SD card in the dock: 20 MB/s write (worth noticing it actually started with 45 MB/s, which is the card's limit, so the lags take in again), 12 MB/s read, same test, pretty weird, as I got 30 MB/s read there before.
With 2GB file I got 15-16 MB/s write & 10 MB/s read on SD, not sure why reading speed dropped that much, but I think I tested it on NTFS a few days before and now it's re-formatted to FAT32.
Edit: So I've just tried the last test with NTFS-formatted SD card and it showed 16/10, so no clue why it dropped this much since my earlier test a few days ago!
I didn't format my card as it came pre-formatted. I'm going to empty it and format it in device and see if that helps. (The card that has been in my SGS2 for about a year performs very badly.... no, let me rephrase that... doesn't perform at all in the TF700T. Let's see if we can get it to shine a bit.
Don't you think somehow caching is involved as the file copying goes steady and then stalls and seems to stop for a whileand then goes again. As if a buffer fills in and one has to wait for it to be persisted in the storage?

Yes, I do think it has to do with (shared?) caching, and yes, the most frustrating aspect of it all is that the damn thing just hangs up sometimes.

1) Why isn't ASUS bombarding us with promises that they are looking into it, in an attempt to retain market share?

1) They're probably quite busy with the Nexus at the moment. Furthermore, seeing that the Prime suffers from very much alike I/O issues that haven't been fixed as far as I have been able to find out, they probably don't care as much as we would like.
2) No one can tell at the moment, but let's keep our fingers crossed that it is software-related and thus fixable by either ASUS -- eventually -- or by custom ROMs. It seems that some custom ROMs for the Prime have significantly improved on its I/O (e.g., AndroWook).

On the SGS2, the standard camera app makes the shutter sound as well. That has been modded out by several developers over there, so I guess it is possible.

Could anyone please follow ganja's lead as well and report back in here? Either it's wishful thinking or it does indeed help quite a bit. I suspect I'm just going crazy, since I did get a few errors in the script's execution -- I have been unable to correct all of them, but maybe some people more knowledgeable than me can see if this actually works (and what the fixes, if at all necessary would be).
The installation tutorial referenced in the thread ganja linked to in his other post is a nice guide to have. Again, seeking in video and such seems to be a lot snappier (almost instantly). Opening QuickPic (a gallery app) in a folder with HD wallpapers is really fast (I had never opened that particular folder before, so it had to render all thumbnails).
I'm not sure if I'm just losing my mind and seeing ghosts. I'll hold off on that judgment for now.
Thanks, ganja!

Now here's the catch why would Asus uses a such old kernel revision while there are latest and current and stable versions available.
Since 2.6 has been a deprecated branch and it is no longer being developed why has Asus create a hassle for its own brand name, why would Asus put a old kernel which the base code was release in Dec/2003. And to quote from wiki...
17 December 2003 - Linux 2.6.0 was released (5,929,913 lines of code).

Why would Asus created a Tablet which features current H/W designs and still uses the old 2.6 deprecated / unsupported kernel???!
This is what puzzles me.
If you do a bit of research you will find this email from Linus himself stating that the old branch is ___in THE PAST___.
Quote again...
As of 2012, the Linux 3.2 release had 14,998,651 lines of code

This email was back in 2011 ...
https://lkml.org/lkml/2011/7/21/455
So what has Asus being doing was designing the HW along with the Linux kernel through out the past several years and came up with this solution ?? Would rather amazes its customers.
Anyways what I'm trying to get the message across is that Asus should have being kept up with technology and bit of quality control and the design.
Edit:
Also this kernel would be insecure and should be exploitable...
Nevertheless a device based on 2.6 would be suspect-able to security risks.

Poor WIfi speeds with CM7.2

Hmmm, I'm in a bit of tough spot.
My Wifi speeds are horrible on a CM7.2 ROM. I'm using a custom rom (from cm forum) that someone built to solve the bad bluetooth headset profile that was regressed into the cm7.2 release. I need cm7.2 cause its' bluetooth also supports HID. Unfortunately, wifi speeds suck in this rom. I can't remember whether the cm7.2 stable had poor wifi speeds.
Does anyone recall what this wifi problem was, and how to fix it?

It's actually in the 3G TurboCharger script, but it is on the thread you linked to.
Thanks, I'm reviewing those scripts.
Additional info... I disabled N support on my AP and my wifi throughput increased from 300-1000 kbs to a consistent 3000-4000 kbs. So that's alot better. But, CM7.2 wifi consistently shows a ~10DBm sensitivity deficit compared to another phone sitting next to it. Also, the Evo Shift stock ROMs sensitivity was more on order with this other phone. So I don't know if the sensitivity deficit is a bug, or part of the power\battery management.
I'm new to CM7.x, so I don't know how I can best test these thing. If I plug the phone in, does it automatically run in "Performance" mode for all features?
The issue I'm facing is I'm trying to use GrooveIP (VoIP) over Google Voice. I was having issues with this phone, and I beleive they were related to the wifi performance.
Any other suggestions for testing or debugging?

As I continue to investigate this wifi issue, I discover that this CM7.2 has no tiwlan*.ini anywhere on the system. Other "slow wifi" reports mention using a CM6.x tiwlan.ini to fix CM7.2 wifi issues.
Can anyone confirm that a CM7.2 ROM should have tiwlan.ini? Where is it? The only file in /etc/wifi, /system/etc/wifi on this machine\rom is wpa_supplicant.conf.
What I'm really looking for is a ROM that: supports all the standard evo shift hardware stuff (inlcluding wimax), plus, bluetooth HID. It be great if it also improved on battery life.
Any contenders\suggestions?

I don't know if you have any options with all those on the Shift.
If you are having trouble with CM7 not working well enough for you then stick with a STOCK based sense rom, every asop GB rom is based around the work done on CM7.

I would suggest strapped365's 2.77.651.8 [Rooted Stock-O.T.A] Rom, or Chad The Pathfinder's Stock Mod [SENSE 2.1 | 2.3.4]. There are quite a few others, these are just two of the latest that are quite stable .
Thanks for the ROM suggestions. I actually have the StockMod as my Sense rom for when I have to update Profile and PRL (I recently switched to Ting... so far, so good).
I've been able to poke around a bit down in linux on CM7. I'm suspecting the bcm4329.ko driver has some config wrong in it, but I don't know how to t-shoot settings really. Since the sensitivity is down by ~-10dBm, but otherwise working, I almost think misconfigured antennas or something. "iwconfig eth0" often reports relatively high "Noise level" and some "Tx excessive retries" although I don't have lots of 2.4GHz equipment competing for the spectrum (afaik).
Regarding the linux layer in Android, do both CM and Sense use pretty much the same implementations with regards to (wifi) hardware, or do they use different "management" interfaces? I guess CM is the one that departs most from "stock", but I don't yet have a feel for whether these departures are mostly in the Android layer, or whether they go deep under the hood into the kernel.
This "low-sensitivity wifi" issue is a widely reported issue thru all makes of phones and versions of (at least) CM, but I have yet to come across any positive diagnosis of the source of the issue (although, given the reports, I suspect a common cause). My hunt continues. Seems all the later dev of CM forgoes wimax functionality... and while wimax hasn't proved to be widely available, it does exist in my area, and 3G is so saturated that it's worth trying wimax when available.
Thanks for the help,

Slow WiFi on my OPO

Hey guys,
Just noticed today that my wifi download speed is horrendous when I do tests on the speed test app. I'm constantly getting about 6mbps while other devices get well into 30mbps. Weird thing is, my upload speeds seem fine. Only the download is slow.
I'm running on stock 30O, with WiFi optimization off. I have tried another router, another device(s) so the problem seems to be my OPO.
This is really annoying! my LTE speed test is fine so it's just the WiFi speed.
I'm standing right next to the router with full reception and i'm still getting only 6mbps.
Does anyone have any suggestions?
Are you using any custom ROMs? If you use a custom ROM, you can try changing the TCP algorithm to any other algorithm to see if it would be any different.
That was on Wireless-N on my ASUS N56U http://i.imgur.com/1dqSI3b.png

I was on stock.. i flashed Mahdi last night and the problem seemed to fix itself...
I'm getting 30mbps now... which is normal for my wifi. Although i have a 200mbps plan... my router sucks!

how do i change the TCP algorithm?
Much appreciate your help!

You need a custom kernel that has this functionality and then a kernel tweaker (such as Trickster), you can tweak around with the TCP and see if it does any changes. It did for me.
Franco Kernel has this functionality if u want to give it a try on various TCP algorithms. theres one named highspeed is which i used.

Ahh thanks man! I'll give it a shot!
Any idea why the stock rom was giving me reduced speeds though? So weird!

No idea, a lot of the custom kernels include newer commits from CM. So it'll be fixed by next OTA. By using custom ROMs/kernels, you get newer commits that fixes bugs, but at the same time, while you fix bugs, new ones appear.
But whats the fun in software that is not buggy?

Did you try going to Advanced Settings in WIFI settings? WIFI optimization is on by default to save battery, but it makes WIFI glitchy, especially with YouTube. I almost bought another router before I figured this out.
