Does the Tf300 have the I/O issues of the Tf700?

I have the tf700 and the lagginess caused by I/O is driving me nuts. The latest update hlped at first but now i am not sure, becuase the lagginess especially with browsers are still there. That may be due to the Tegra 3 on a 1080p screen vs. 720p screen?
Does the TF300 have the same I/O issues?

Yes, if you are rooted you can try Browser2Ram to fix the browsing bug. My tf300 is smooth, but I also use a custom rom.
I had the Acer A700 and it was laggy as hell, so I am going to guess the 1080p screen may be too much for the Tegra3.

I rooted my device and used the minor tweaks & speed adjustments that are in the development section. Also installed browser2ram. Still not flawless but much better.

There's a link somewhere in this forum that asus has recognized the issue and is working on a fix. I don't know if thats completely true or not but is still nice to hear. With the tf700 you will eventually have some good kernels i'm sure which will allow you to mount /cache /system to your sd card which will greatly improve your I/O especially if you have a class 10 sd card since they have quicker read/write speeds than the internal memory!

Here's a blog post regarding this fix. No sources listed, though: http://mark-tech.blogspot.com/2012/08/tf201-update-coming-to-address-io.html

Is the IO issue a stock rom issue? I have been using Jellybean for a while and don't notice any lag.

AFAIK as I know the I/O issue is due to stock kernel not stock rom. As of now there aren't any custom kernels out there for the TF300, so the improvement in performance you see is due to tweaks done by the rom dev and JB being faster as is. I don't have lags either and I'm on rooted stock rom with a couple of tweaks.
Run a benchmark and look at your writing and reading speed of the internal sdcard and SQlite scores. You will see that they all score very low compared to other devices. You will notice lag when for example extracting a large zip archive (1gb) from and to the internal sdcard.

Recent htc one x 4.0.4 OTA dramatically improved performance, noticed almost 1000 points more in quadrant mostly in the I/O area....so yes it' s software and yes can be fixed via updated

Strange. I flashed the clemsy kernel (1.8GHz) and my quadrant score was only 5400 on performance Did you set your min and max both at 1.8?

The highest Ive got was 6247 with his kernal on performance mode and had data 2 sd also installed. Both of those tweaks help this tablet. I have also noticed that you may want to restart the tablet once after you flash your device with these tweaks. You can get to these speeds! I love my tablet at this point.

Been on Scotts ROM for a week or so awesome I must say.
I just flashed Clemsyn's latest and have been seeing lower scores in Quadrant below 5000 a few times.
I have the 1.8 OC the overall scores have dropped dramatically.
Guess I'll keep fiddling with things till the scores get back up there.
I think it might be System Tuner Pro bugging something.
Other than benchmarks the tablet still rocks!
Very smooth only 1 FC\reboot so far and that was Quadrant itself .. lol
Haven't had an ANR or reboot since flashing CleanROM-2.3 with Clemsyn's latest.
(except for 1 running Quadrant)

I dont have data2sd just cleanrom 2.3 and the clemsyns kernal. Here is my sunspider scores and my quadrant again

Yeah just keep messing with it, one question. I know a lot of people have ran into the bootloader preventing them to get higher clock speeds. Do you know if you are on the latest bootloader? Also do you know for sure you are running at a 1.8 OC? To check you can use the app Stability test and it should give you a frequency reading at the top.
I have been running ClearROM for about 3 days now and 2 days ago switched to Clemsyns kernal. I definitely think that CleanROM is a very smooth ROM however once I flashed Clemsyn's kernal I had a new meaning to smooth. Absolutely loving my tablet experience now. I went from the Prime to this speed demon, couldnt ask for a better tablet right now.

This is the latest bootloader.
I could try reloading cl2.3 maybe...
System tuner is reporting 1.8 @ 41 degrees celsius...not too warm for an overcluck.
I want to see if YouTube is affected by these tweaks.

Update!
I had things pretty goofed up on the tabletron model TF700T last nite...I got tired of screwing up so I gave in.
Today I just started over and went straight to JB .18 seeing how slow and crappy Jellybean was for me I re-rooted using hiemanshu's tips.
Anyhoo short story longer: After a new install of CRom 2.3 and Clemsyn's Kernel me is happy!
Quadrant shows 6150 overall with IO at 7267 :cyclops: ... and that's in balanced because I never remember perf mode.
Sooooo we R good here...
Whew!

Glad you got it working man! I really havent seen a difference in performance mode and balanced mode when running the quadrant tests. I dont know if anything is actually running faster since the cpu is overclocked to 1.8 either way. The only way to change it I think is with setCPU or a similar app.

CleanRom includes the stock kernel. FlashCleanROM 2.3 ist, then Clemsyn's kernel. You may lose some of Scott's tweaks but the Clemsyn kernel makes up for it!

Also, System Tuner may not play nice with either ROM or kernel...that's what I heard.

Yeah I know what you mean, the breaking point was on the verge. Although Im sure that with all the fuss it gave you, it was worth it in the end.

What significant (everyday user) changes do you see with CleanRom and the kernel flash, as appose to say, not having it rooted? Browser faster? What do you really see in everyday use?

I don't see much need for data2sd myself, with fsync disabled on cromix, and hunds kernel I am gold. I suppose if you want to tweak to the max, do both, but data2sd just looks like a cluster f*** to me.

I read in the Cromix thread somewhere that if your tablet freezes, having fsync disabled can corrupt your database. Will this brick the device?

Nah, most that happenes is you need to wipe and reinstall, but I have used the tab with fsync off for 7 months with no issues.

In case anyone needs more information about fsync, read my 2 answers in this thread: http://forum.xda-developers.com/showthread.php?p=33381928

I am running both on CyanogenMod. Fsync is turned off and my data is on SD. I have never experienced data loss, but also didn't have sudden reboots. Only while experimenting with voltages and CPU frequencies.
I got to say, even though it is a pretty slow card this tab is flying.

Its worth noting, with the topic, that you should always have a nandroid backup, which I recommend copying to at least one other device (just in case) and make sure to keep backups of pics, docs, etc also. This way, even if you have a problem, you can always restore pretty quickly.

[Q] Custom ROM CROMi-X or Cyanogenmod

I want to start experimenting with custom ROMs, and figured CROMi-X or Cyanogenmod would be a good place to start. What would be a good one to start with, and what are the benefits of one over the other?

I can't speak to the differences but i recently did my first root and flash and really like CROMi-X, the performance is leaps and bounds better than stock and its easy to install
Sent from my ASUS Transformer Pad TF700T using xda app-developers app

I'm thinking CROMi-X will be the way to go since it's close to what I'm used to. I just don't want to get one set up the way I like it, and then change ROMs because I find out I like the features of the one I didn't install.

If you are looking for a look and feel close to stock, just much, much faster, go for CROMi-X. It's also more stable than CM because it based on the Asus framework.
If you want to customize to the wazoo and don't mind the occasional hiccup, go for CM. It is build from the ground up and offers way more options to personalize the tablet.

Unfortunately, I have to say that CM is even slower than stock. Very annoying. CROMi is way better and faster. Did not try the X version yet but it should be fast a well. Please let us know about you experience either way.

Er....
Kernel - 5 choices now I think
DPI - Pixel definiton
Resolution 1080p or 720p
Which Asus Apps you want / don't want
Which Google Apps you want / don't want
5 different boot animations
Loads of performance tweaks incluing overclocking, underclocking, over volting, under volting
Additional options and menus
Full theme support through the excellent Colour Theme Mod (Change colours of almost anything and battery icons etc)
And loads more.
In fact I probably went a bit mad on the number of permutations I offer! It's a wonder they all work!

NTFS supported kernel?
Which of the cromi-x kernels support a 1Tb external drive? I flashed the ROM but I can't remember which kernel I picked during the installation. It couldn't read my external drive or a new 64 Gb microSD. I flashed back to stock which does support both BUT it is too darned slow!!!! Which should I pick next time?

CROMi-X
berndblb probably summed it up the best in Post #4 but for me the only customROM choice is CROMi-X!!!
There are plenty of options and choices from rock solid stable to flying out of your hand fast but the most significant reason is you get a personalized team devoted to CROMi development, From the Master sbdags to the kernel developers, the software contributors as well as the testers. They seem like one big family... You basically get a bonus feature of an "Android Classroom" with this ROM. I have learned more about my TF700 from just following along with the OP's for all the CROMi-X versions.
Good luck and have fun with CROMi-X

I've been using CROMi-X since I got my tablet last christmas. I love all of the customizations that they make available, plus all of the kernal options that they include.

I do like CROMi-X, using 5.1a. But I must have something not tweaked right. I still get it being bogged down when a software update from the Play Store is downloading. Also Lookout software checks everyone, so I guess that could be the culprit. But other than that, I do see some speed improvements over stock. I still have all but 3 of the Asus Apps installed. Just rooted and unlocked this week. So need to figure out what I really don't need in terms of apps.

optimizing loop
Upgraded to 5.1a odex and on every reboot go thru optimizing applications. Installed 5.1a deodex and it boots just fine. Reinstated 5.1a odex and does the same optimizing loop on every boot.

[Q] CROMI-X benchmark low?

I recently flashed CROMI-X, and I'm loving it so far; huge improvement over stock, thanks to all involved! A quick question, though: I've been running the Quadrant benchmark, and averaging around 4400. That's a big improvement over stock, but seems quite a bit lower than any scores I see posted here; could I have messed anything up during the install, missed an important setting, ticked the wrong box, anything like that?

Yeah, if you don't have overclocking, you won't reach the benchmark results posted.
But then it is all about usability, so if you are happy, no reason to chance damaging your device by overclocking.

If you are content with the functionality then stick with that. But if you are experiencing lag and sluggish performance then an oc'ed kernel is the only option you have to give it a boost.
I ran CROMi-X with Hundsbauh's kernel for a year, updating with each new version. I never experienced any problems while running oc'ed and the performance was great. Hundsbauh's includes an app where you can tweak the clock speeds for both the CPU and the GPU. e.g. I set my Balanced Mode to 1500 Mhz / 484Mhz and ran that way most of the time with no issues. It was a nice balance between performance and battery life.
That said, each device is different and your results may vary, but you should be safe using CROMi-X with Hundsbauh's kernel set to a reasonable overclock. It won't let you go higher than 1700 Mhz / 520 Mhz.

After my original post, I tried switching to _that v7, and saw a nice bump in performance, though I'm not sure exactly what it's overclocking it to; I may try Hundsbuah's kernel, I like the idea of tweaking the speeds myself. I had been under the impression that _that's was a bit more stable, but it seems many people use Hundsbuah's without issues.
