Most of the recent WM6 rom chefs have been advocating making NO performance tweaks, in favor of keeping as large a RAM pool as possible. As I rarely need 30mb to run a program, I am happy to give up what I don't need if it will help get data back and forth to the SD card and so on faster. Has anyone got thoughts or data about this? I don't own a benchmarking program so I can't check it out directly. I have been making all the tweaks anyway, but does it matter?
Thanks for your thoughts!

I agree completely! I'd like to see a WM6 ROM with all the performance tweaks and 8 MB page pool. I know jwzg is working on an 8MB pp ROM based on Faria's up coming Vanilla WM6 ROM.
Check out this thread for more info http://forum.xda-developers.com/showthread.php?t=299584&page=10
Thanks for the link. I really don't understand the drive for smaller and smaller page pools either...
Some Answers!
OK, here is my contribution to the WM6 literature...
I am running battery status 1.04 beta 3 with the following settings in all tests: cpu speed 247, cpu scalar min 143, boost 278. set on wakeup, remember last speed. My base setup is as per my signature. I ran SK Tools v 3.1.1.0 in demo mode. I also removed the HKLM\init launch100 key in both cases.
All tweaks, No tweaks
Integer (moves/25us) 134.0864, 134.4001
Floating point MWIPS 3.490, 3.489
RAM Access speed index 345, 328
Draw bitmaps speed index 503, 522
Main storage (w) KB/sec 607.78, 612.14
Main storage (r) KB/sec 3670.25, 3469.23
Storage card (w) KB/sec 412.76, 423.11
Storage card (r) KB/sec 3353.71, ! 1119.13
As you can see, the major difference is in the storage card read speed. This led me to retest using only the SD card speed tweak, and no others. Surprisingly, the result was unchanged from using no tweaks! So, likely there is some interaction with the other file system tweaks that is involved. (See the wiki-WM5 performance tweaks). At some point maybe I'll try to pin it down further.

Ed

When I was using NotTooSmart's ROM, it had some performance tweaks. I don't have a benchmark prog but it was definitely much faster. I would say it's comparable to when I had it overclocked to 234-247MHz...
I believe what made the most difference was the System Cache... I lost ~10MB of RAM but the ROM was flying... Start up was scary though... I think it went <2MB w/ the progs I had...

A lot of people tend to be RAM fanatics... that's probably what drove cooks to have smaller and smaller page pools... Another thing is people and numbers.. many tend to feel the bigger, the better.. High IPL/SPL, High Radio, High OS, High Storage, High RAM.. I think you get the picture.. =P
Update on tweaks
I think I'm near the max. I maxed out the file cache, and filter cache, kept the SD cache at 256 and re-ran the benchmarks. Slightly higher numbers all round, but a dramatic increase in SD card read rate, now up to 6.5 mb/sec! I would expect this would speed loading those big programs and files from the SD card, and is 6 times the "stock" speed!.
Regards,
There was a post a few weeks ago (I think) where someone did comparisons with playing with PagePools and the performance. They compared 4MB, 6MB, 8MB, and 12MB pagepools. As I recall there was very little difference between 12MB and 8MB performance. I think 6MB was the worst of the 4.
Again this was all from memory, but I just remember after reading that, I no longer was that concerned about the differenence in performance over the added extra memory available by dropping to 8MB.
Performance tweaks
Actually, in thinking about the issue, it occurs to me that the standard benchmarks we are using (SPB Tools) don't measure things that would likely be changed by a change in page pool. CPU calculations, memory access speeds, would not change by changing the page pool or buffer sizes. The only measurement which would change would be the speed of swapping programs and data in and out of memory (by suppressing the actual need to do so) or accessing the memory card. However, these things *would* impact on "real life" apparent speed of the device in activation of programs and quick response times.
Thoughts?
Forgive my obvious ignorance... This is the closest thread I have found for my search, "SD card speed tweak" so can you please help me? point me to the tweak to speed up my SD card?
thanx in advance!
Re: Speed tweaks
Sure, If you want awesome numbers on SK Tools SD read benchmark, (particularly when combined with overclocking) make these registry changes:
HKLM>Drivers>SDCARD>ClientDrivers>Class>MMC_Class:
Change BlockTransferSize to 256 decimal
HKLM>Drivers>SDCARD>ClientDrivers>Class>SDMemory_Class:
Change BlockTransferSize to 256 decimal
HKLM>System>StorageManager>FATFS:
Change CacheSize to 4096, 8192, or 16384 decimal
HKLM>System>StorageManager>Filters>freplxfilt:
Change ReplStoreCacheSize to 4096, 8192, or 16384 decimal
The larger the numbers the faster the benchmark. However, some of the other benchmarks run slighly slower, and I'm not sure I see significant "real life" improvements in responsiveness. I'd be interested in your impressions. One thing to watch out for, particularly when using the 16384 settings, is that available memory can drop to "dangerously" low levels on start up from soft reboot. If you're using batterystatus you can monitor this. As long as you stay above 2mg or so at the minimum you're ok, as the situation resolves after the start up routines finish. If you do go below, I've had the screen blank temporarily and hang for a moment, but it eventually booted fine anyway.
Have fun!
Thank you for your prompt and courteous answer!! I am still learning this PocketPC stuff. Someday I hope to be able to contribute. It already seems faster!
email tweaks
is there anyway to make my pics in emails auto download?
(instead of having to click "download pics" every time...)
and to create shortcuts to my text messages and other applications, how can i do that?

This question is slightly offtopic, but I'll answer you anyways.
Go to the email account you want to change:
Menu/Tools/Options/Choose The Account (it will take you into email setup):
Next/Next/Next/Options/Next/Next/Download size limit (drop down menu - choose what you want)/Finish
Hi,
I saw the benchmarking results that you guys posted and the difference between "with tweaks" and "without tweaks". The numbers sure show a difference with the benchmarking results but what i'd like to ask and what i'd really like to know is - have you noticed a significant difference in actual/real life performance on ur wizard? Was it obviously faster?
I mean, for me and IMHO, i'm not much of a fan of "benchmark" results and all that unless I actually see a "real" difference in speed when i use my PPC. I don't think i'll go for the performance tweaks if i'll loose 10+MB of RAM and am only able to see "benchmark" results being better instead of overall actual performance. That's why i'd like to get ur inputs on this whole performance tweaks thing...is there a noticeable difference in speed? (not just benchmark data)
WM 6.1 Tweaks
Hi,
Even the thread is quite old,
after some time of using WM6 and 6.1 and test meny mor etweaks, there I post some of them who i found usefull.
TKS to all contributors form xda or another.
1. Stop 3G services: settings\phone\ HSDPA must be disabled; RAT set to GSM; the internt still accesible trought GPRS for the most operators
Result in: less batery consumption 1-2 days stdby increase to 3-4 days
reduce blockings and wake-up problems
2. Disable Power management for SD card: use poket toolman or others and uncheck Enable Power Mgmt for SD card; or use regedit and change to
[HKEY_LOCAL_MACHINE\Drivers\SDCARD\ClientDrivers\Class\SDMemory_Class]
“DisablePowerManagement“=dword:00000001
Other option:
Change reg into
[HKLM\System\StorageManager]
“PNPUnloadDelay“=dword:8196
[HKLM\System\StorageManager]
“PNPWaitIODelay“=dword:8196
Note that the 8196 should be entered as a DECIMAL value. The HEXADECIMAL (HEX) equivalent is 0×00002004.
Result in: Less blocking and sd diseaparing fix or slow upload sd when wake-up
More consumption on batery, about 10% more, but with tweak 1 still OK
3. Uncheck today timeout: settings\items\ uncheck Today timeout
Result in: less delay when a phone call income o r standby resume
4. Try to instal the alarm programs and sounds files direct into main memory instead of SD; to avoid sd blocking when standby resume
5. Install .NET Compact Framework 3.5 (last vers) to your device, as:
1. Download .NET Compact Framework 3.5 from Microsoft and save it on your PC.
2. Run the downloaded MSI file and let it install.
3. Connect your device to Activesync/Windows Mobile Device Center and finish the automatically launched installation on your device.
4. Soft reset your device.
5. Open a Registry editor and navigate to HKLM\Software\Microsoft\.NETCompactFramework where you will see two entries for the (now two) existing version references: the old one, which came with your device and the new one you just installed.
6. Change the DWord value of 3.5.7283.00 from 0 to 1 (thus enabling it) and all the other values (i.e.: 2.0.7045.00) from 1 to 0 (thus disabling it/them).
7. Soft reset your device.
Result in: shorter time (gain 0.5 sec) to navigate trough windows menus and buttons actions.
6. Activate lock applet on today menu; Without this function when the phone is in stand-by and a call income the phone delay has about 8-10s to wake-up.
Result in: the wake-up on call is shorter (gain 4-5 sec) than without this lock checked in today settings; somehow WM use this library to pass trowght to wake up.
7. Speed-up the SD card read; tks to edhaas contributor from xda-developers.
Action: increase some SD cache into registry:
a) HKLM>Drivers>SDCARD>ClientDrivers>Class>MMC_Class:
Change BlockTransferSize to 256 decimal
b) HKLM>Drivers>SDCARD>ClientDrivers>Class>SDMemory_Class:
Change BlockTransferSize to 256 decimal
c) HKLM>System>StorageManager>FATFS:
Change CacheSize to 4096, 8192, or 16384 decimal
d) HKLM>System>StorageManager>Filters>freplxfilt:
Change ReplStoreCacheSize to 4096, 8192, or 16384 decimal (16384 is dangeours high, some blank screen at startup)
a), b) settings are regulary set by default to 256; c), d) is by default to 0, so change-it and see if gain some perf.
All of them has tested and works fine.
Apply and now I found my i-mate ultimate 6150 OK, instead of first phone impression when I blame-it.
Did a light weight search here I don't see anything applicable.
Realizing the Linux\Android kernel is very memory friendly.
I had 1 or 2 questions.
What type of apps will put the most drag on processing as far as tasking on the Infinity?
Gaming for sure maybe.
Haven't gamed much lately so perhaps not an issue for me.
My uses are browsing like most.
Reading technical PDFs with diagrams and charts.
Letter writing.
Editing photos.
Electronic mail.
(I'll say I don't have much slowness with the above)
How are applications designed for speed?
Which type of apps present a light load on the system?
Do faster applications crash more? (with the Infinity specifically)
What are the major differences between Linux and Android?
I know a googsearch could yield info.
I just thought I could call on you guyz\galz for a spirited discussion.

By using fast algorithms and fast programming languages, and avoiding stupid things. Since the CPU has a fixed maximum speed, the only way to make an app faster is to execute fewer instructions to achieve the desired effect.

Correctly programmed apps will only load the system if they have a reason (meaning, they do some work for you). Depending on what the app is supposed to do, this can be a light or a heavy load.
Reading technical PDFs with diagrams and charts -> will be a heavy load while rendering a page, and should produce virtually no load while you are reading.
Letter writing. -> should be a light load, since it will wait for your keypresses most of the time.
Editing photos. -> photo manipulation can be a heavy load, since calculations have to be applied to millions of pixels.
Electronic mail. -> see letter writing. Except if you send big attachments, then this will be a heavy load for the storage subsystem, but a light one on for the CPU.

No. Buggy apps crash more. If code is correct, it does not crash. As written above, slow applications do not really run slower or safer, they just waste more time.

The Android kernel is a derivate of Linux that has some additional features for memory management, interprocess communication and power management.
The userspace part (everything running on top of the kernel - system libraries and applications) is very different.
Thanx!
Good information for me.
I've looked around and couldn't find a viewer for postscript files. Is there anything around?
ghostscript is available under GPL, so I figure it should be possible to create something. Is there some legal/licensing obstacle I'm not aware of? Is there a technological obstacle?
This was asked time ago in the asus transformer forum, with no conclusion: http://forum.xda-developers.com/showthread.php?t=1483244 . As noted there, there is at least one service that sends the file to a server for conversion to pdf. Apart from the inefficiency and requirement for network connectivity, this also results in a pixellated version of the files (If there had been an option to setvery high resolution, the cost would be huge files). Normally, postscript images allow arbitrary scaling.

My first Android app, initially created out of a real need, but has grown a bit since.
My app allows loading or pasting of text csv or other column formatted text files to display the data either as y-t plots or arbitrary x-y plots.
Surprisingly, I couldn't find such an app. I could only find function plotters, which this app is not.
At first, I needed this app to show experiment results to a professor, but I now use it at work on my tablet instead of printing graphs, allowing me to interactively demonstrate points of interest in my analyzes.
It is written with large data in mind, using C++ and OpenGL for speed and tight memory usage.
It is available on google play under "PlotimFree" but I also attached it here.
Created graphs can be either exported to PNGs or saved as binary files for later fast re-loading with all configurations and parameters.
I use it mainly on my 10" tablet, but I tested it on a few phones and tried my best to make it useful on small screens.
Hi,
I have a DELL Inspiron 15-3567, spec - i5 7th gen, 4GB ram, 512 GB HDD. But it is super slow and I can't even perform normal tasks like surfing the web or watching videos.
How can I improve this? Any help is appreciated.
An absolute low-end device, IMO.
1st thing of all things you could do is to disable all services you don't need. Normal Windows user can safely disable a dozens servives. You may look inside here
