There is no question, XFS and JFS have better perf than ext3. However, in your particular problem, i would look at the FS performances as a last resort. What about the general IO of this box ? (hdd quality , bus speed , etc..etc..). Againm 500 files operations a minute does not sounds to me as a re

Hi, not that i ever tested any of those 2 new filesystem, but i have some troubles to believe that the FS'd be the bottleneck in your scenario; maybe i'm wrong, and 'd be interested to read some tests too though. JeF On Wed, 2003-02-12 at 03:53, Thedore Knab wrote: > I am moving away from using
