Ok last last update... re-applied following reg hacks from

http://pdaphonehome.com/forums/ppc-6...stable-12.html


DSOD RELATED IMPROVMENTS

HKLM\Drivers\SDCARD\SDBusDriver
PowerUpPollingInterval - 2 (Dword)
PowerUpPollingTime - 2000 (Dword)
These settings we're borrowed from the Treo 700w.

HKLM\System\CurrentControlSet\Control\Power\States \Suspend
dsk1 - 2 (DWORD)
Prevents the SD Card from going into suspend; the main cause of DSOD
cam1 - 4 (DWORD)
Forces the camera to turn off during suspend, saving power.

PERFORMANCE RELATED IMPROVMENTS

HKLM\System\CurrentControlSet\Control\Power\States \Unattended
wav1 - 2 (DWORD)
Prevents the sound card from turning off while the unit is unattended mode.

HKLM\Drivers\SDCARD\ClientDrivers\Class\SDMemory_C lass
*BlockTransferSize - 64 (Dword) *If you experience skipping audio try 32 or 16.
Specifies the maximum amount of blocks to send per bus transfer.
** was 16, left @ 16


HKLM\System\StorageManager\FATFS
CacheSize - 4096 (DWord)
Specifies cache size.
EnableCache - 1 (Dword)
Enables filesystem cache.
EnableWriteBack - 1 (Dword)
Enables cache writebacks.
Flags - 68 (Dword)
Specifies filesystem options.
EnableCacheWarm - 1 (Dword)
Preloads the cache upon booting.

HKLM\Drivers\BuiltIn\CameraDriver
JpegBufferSize - 768000 (Dword)
May provide a buffer for the camera allowing for smoother operation.

HKLM\System\StorageManager\Filters\fsreplxfilt
ReplStoreCacheSize - 4096 (DWORD)
Enables the file system filter cache, speeding up overall performance with file mangement.

Reset, and *now* can say aku is faster. Without above tweaks aku2.2 is about as fast as 2.0 with those tweaks, With them, it's screaming.
