My next question... the performance hacks. (a) does increasing the cache take away from the available RAM or ROM? If its from the ROM, couldnt I make the cache sizes even larger, or is there a point in which it becomes excessive/counterproductive. (b) do the performance hacks DECREASE battery life, or no real affect?

ppc link here... http://forum.ppcgeeks.com/showthread...=battery+hacks

this all started on the Q but works on many WM devices. i have been running it on my mogul for quite a while. works great.

this is what is changes...

Speed Hacks

These have been posted elsewhere but the 3rd one listed here is never mentioned and often left out. A shame since it seems to have the most effect!

The following 3 hacks increase system performance and makes the Q more responsive:

Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\GDI\GLYPHCACHE\
Changed limit from 16384 to 32768

Navigate to: HKEY_LOCAL_MACHINE\System\StorageManager\FATFS
Changed - CacheSize to 4096

(NEW!) Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\StorageManager\Filters\f sreplxfilt
Change “ReplStoreCacheSize” dword decimal value to 4096 or 8192 (edit: I find 4096 best, g-funk finds 8192)

Battery Life

A couple of us have tested this and found a nice increase in battery life. On my Treo 700 it seemed to do nothing but on the Q it greatly helped (I ran for 12 hours yesterday push email in a low signal environment and stayed at 4 bars battery--normally would have been at 2 or 3)

"...simple registry trick and hack that will enable power management on several communications protocols to save and conserve the battery life, and thus extend and prolong the battery of the Windows Mobile devices."

Navigate to: HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms
Default value type and value are
“DisablePowerManagement”=dword:1
Change to
“DisablePowerManagement”=dword:0

Navigate to: HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms
Default value type and value are
“DisablePowerManagement”=dword:1
Change to
“DisablePowerManagement”=dword:0

Navigate to: HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms
Default value type and value are
“DisablePowerManagement”=dword:1
Change to
“DisablePowerManagement”=dword:0

Navigate to: HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms
Default value type and value are
“DisablePowerManagement”=dword:1
Change to
“DisablePowerManagement”=dword:0

in the zip file below is a cab. move it to your device and tap to install. remember to wait one minute for reg changes to take effect and then do a soft reset.

enjoy, cody
