You can change the memory used to cache fonts glyphs, this allows you to use more memory to speed up the display.
Browse to HKEY_LOCAL_MACHINE\SYSTEM\GDI\GLYPHCACHE\
You can change the "limit" value :
4096 : this will slow down the display, but use less memory
8192 : this is the default value on Pocket PC, average memory/performances
16384 : this will speed up the display, but use more memory, twice the default Pocket PC value
I had mine set to 32768, until I realised half my ram was fake!
Enable FileSystem cache
To enable the FileSystem cache, speeding up overall performance at the risk of the cache not being written on a sudden reset:
HKLM\System\StorageManager\FATFS\EnableCache = 1 (DWORD decimal)
To disable again:
HKLM\System\StorageManager\FATFS\EnableCache = 0 (DWORD decimal)
Note that by default, the cache size is zero, and you will see no effect. See "Increase FileSystem cache" below to increase the cache size.
Increase FileSystem cache
To increase the file system cache:
HKLM\System\StorageManager\FATFS\CacheSize = 4096 (DWORD decimal)
To return the file system cache to zero:
HKLM\System\StorageManager\FATFS\CacheSize = 0 (DWORD decimal)
Don't set it too high, it will eat your ram, I set mine to 256. My RAM free went from 26.7 to 25.9. You'll have more leeway if you have a real 128MB machine
