The reason of BA WM5 slowdown

[mamaich]

Microsoft has a diagnostic tool DevHealth.exe (sorry, I cannot publish it).
Here is the output on BA:

Look at the "Paging Pool" line, it is only 2.01 Mb. On HTC Universal it is 4.8 Mb, on one of the DELLs it is 8 mb.
The large the paging pool is, the more code pages can present in RAM simultaneously -> the less loads from slow ROM -> the faster the device is.
BA has 128 Mb RAM, so we can increase it safely to 8Mb (larger value would not give noticeable improvements).
One note - I don't know the addresses to patch in ROM, so someone should find how to increase pool size.

The true GURU is back!
its really Nice to see u again mamaich!... hopes u can help us here in BA...

[MasterMerlin]

Another step forward .. thanks to all of you guys.

Were you able to get your hands on nkDebugX (available as a powertoy)?

[a771la]

ok

how to increase pool size ? :evil: :twisted:

I never heard about this tool.
Regarding paging pool size:

0000437056: 28 A0 1F 80 FF FF FF FF │ FF FF FF FF 9B 4F FF FF  (аА        ЫO  
0000437066: 64 B0 00 00 64 00 00 00 │ 08 DF 1F 80 00 00 20 00  d░  d   ▀А
0000437076: 00 00 00 00 C4 6B 1D 80 │ 50 C0 1D 80 9C F0 1C 80    ─kАP└АЬЁА

At address 0437072 of NK.NBA you see 00 00 20 00. Try to increase the value to 00 00 80 00 (it would increase pool to 8 mb). If this works - you'll see the noticeable speedup during boot process, and the RAM amount displayed in "memory" CPL applet would decrease by 6 Mb.
You may play with higher/lower values, 8 Mb should be enough in most cases. But BA has lots of RAM, so you may try 16Mb.
But the device may fail to boot. In this case connect KITL and tell me the error message, it is possible that some other addresses should be also changed (or maybe I've found an invalid address, I was looking in Universal's ROM).

I edited nk.nba as you advised and flashed my BA with edited Helmi 1.3.1 ROM.
Super fast!!!!!
It works!!!!!!

Thanks GURU mamaich!!!!

[vivi]

And RAM is reduced 6 MB as you mentioned.
From 91.16 to 85.14 MB.

In my rom, its make faster just like wm2003... :wink:

Hey Helmi
I agree with you.
Mamaich is GURU.
And you too.
Thanks all.
Hope you will release a new ROM with this patch soon.
:wink:
