Try to add new DWORD value:
HKEY_LOCAL_MACHINE\System\StorageManager\FATFS
BufferSize=0x900 [that is 2304 decimal]
[add BufferSize, wait 30 seconds and reboot :)]
Use value between 0x800 and 0xA00.
If buffer size is not defined default value is 0x20 [==32].
SPB benchmark told me, that some file operations could be faster:
Write 1MB file 0,39%
Read 1MB file 5,04%
Copy 1MB file -1,31%
Write 10KB x 100 files 12,23%
Read 10KB x 100 files 22,31%
Copy 10KB x 100 files 8,44%
Directory list of 2000 files 38,05%
Internal database read 2,50%
Don't use BufferSize>0xA00 - results are not so good [due to buffer management overhead].
BufferSize<0x800 - results are not so good, too.
BTW. Increasing CacheSize above 0x1000 [decimal 4096] doesn't increase file system performance.
