Does anyone have any data points on XFS in this regard? I agree that ext2 is faster than ext3, and ext3 probably has lower latency than reiser3, but I have no info at all on XFS. My JFS experience is all on AIX, as well, so if anyone has that info it might be interesting as well. -- -bill davidsen (davidsen@tmr.com) "The secret to procrastination is to put things off until the last possible moment - but no longer" -me
