[MDA III, XDA III, PDA2k, 9090 Software Upgrading] Brazilian Joe:
I decided to start a new thread to experiment instead of posting inside the 1.3 thread.

Even with all this cache boosting, it seems the reported free memory is still above 60MB.

That's with no today plugins running.

Here are the settings I am testing:

[HKLM\System\StorageManager\FATFS]
"BufferSize"=dword:0x000400 (decimal 1024) (old:256)
"CacheSize"=dword:0x004000 (decimal 16384) (old:4096)
"DataCacheSize"=dword:0x004000 (decimal 16384) (old:4096)
"DLL"="fatfsd.dll"
"EnableCache"=dword:00000001
"EnableCache4Way"=dword:00000001 (old: didn't exist)
"EnableCacheWarm"=dword:00000001
"FatCacheSize"= 0x004000 (decimal 16384) (old:1024)
"Flags"=dword:00001006 (writethrough bla bla)
"MaxCachedFileSize"=dword:00020000 (don't cache >128Kb files)
"Paging"=dword:00000001
"PathCacheEntries"=dword:00000400 (1024) (old:256)
"UpdateAcces"=dword:00000000 (do not update access times, should have a positive impact flash wearing)

[HKLM\System\StorageManager\IMGFS]
"BufferSize"=dword:0x000400 (decimal 1024) (old:not sure)
"CacheSize"=dword:0x004000 (decimal 16384) (old:not sure)
"DataCacheSize"=dword:0x004000 (decimal 16384) (old:not sure)
"PathCacheEntries"=dword:00000400 (1024) (old:256)
"UpdateAcces"=dword:00000000 (do not update access times, should have a positive impact flash wearing, not sur if it has any effect on IMGFS)

[HKLM\System\StorageManager\Profiles\FlashDrv\FATFS]
"BufferSize"=dword:0x000400 (decimal 1024) (old:256)
"CacheSize"=dword:00000400
"EnableCache"=dword:00000001
"PathCacheEntries"=dword:00000400 (1024) (old:not sure)

[HKLM\System\StorageManager\Profiles\FlashDrv\IMGFS]
"BufferSize"=dword:0x000400 (decimal 1024) (old:256)
"CacheSize"=dword:00000400 (at the cost of 256 Kb RAM)
"EnableCache"=dword:00000001
"PathCacheEntries"=dword:00000400 (1024) (old:128)

Therewas one single test which simply failed, I don't know why. I believe this failed test is the reason why the overall score is unavailable. But the machine is stable so far, I have no complaints.

The results are the following:

reference machines (from spb benchmark website database):
(1) Compaq iPAQ 3600 Series (2000, 206Mhz)
(2) Asus MyPal A620 (2003, 400MHz)
(3) Asus MyPal A716 (2003, 400MHz)
(4) Fujitsu-Siemens Pocket LOOX 600 (2003, 400MHz)
(5) Fujitsu-Siemens Pocket LOOX 610 (2003, 400MHz)
(6) Toshiba e750 (2003, 400MHz)
(7) Toshiba e755 (2002, 400Mhz)
(8) Dell Axim x51v (WM5, 400MHz, video hardware accel)
AND...
(9) Blue Angel WM5 Helmi 1.3 beta

Spb Benchmark index 1000 1573 1622 939 1610 1225 1073 - unavailable probably because of the database error
CPU index 1000 1858 1796 1202 1813 1838 1234 1646 upper half, not that far from the others
File system index 1000 1092 1205 670 1175 1128 1270 - unavailable probably because of the database error
Graphics index 1000 4034 3954 1367 3943 688 651 1207 before tweaking it was around 850
ActiveSync index 1000 1458 2192 480 1775 1751 1479 3269 WINNER! And i am using USB 1.1!
Platform index 1000 1277 1510 796 1341 1085 850 - unavailable probably because of the database error

There is only one WM5 device besides teh BA, which I collected from this review:

Helmi, can you make a hotfix cab called 'Brazilian_Joe_UNTESTED_performance_tweaks.cab' to apply these tweaks and add it to Helmi 1.3 beta front page, with a big red fat warning?

EDIT: The 'internal database benchmark error' happens even with the default 'Helmi 1.3 beta' registry values, so it's not a by product of my settings. Just to reinstate, even with this error the machine still runs without problems.
