Today i checked with: XFS,JFS,EXT4, Reiserfs
All except Reiserfs (which is significant faster) are slower than EXT3. Don't know exactly how much, because i stopped the test when the time was over the time of EXT3.


The key seems to be DefaultDbCachePages as Claudio wrote. Increasing its value has dramatic performance increasing for the long time HDD operations.

So i am keep using Linux ;)

Thanks to all !
