Thanks Sean,

Somehow the thread got split, I'm not sure why.

New box has ext4 with the barrier bit set. On the other part of the thread I got adviced to check this parameter. It surely helped performance to disable it.

Is it safe to just disable the barriers bit or should I use ext 3 filesystem?

Thanks in advance.
