Hello, I'm running a Centos 5.4 x64 Server with Raid0 HDDs and XFS. I did some performance tweaking according to [1] as performance was not good enough with std. options. Extracting a tar archive with 6.1 million files (avg. Size just below 2KiB) is blazingly fast after the fs has been generated. But after some time while doing deletes/moves (need to sort those files by their contents) the fs performance degenerates quite badly (from 8k file writes/sec to about 200). Is there any way I can find out what the issue is and how I can help it? (I tried numerous other FSs and of those XFS has left the best impression in my use case) Tweaks I used: mkfs.xfs -b size=2048 -l size=64m mount -o noatime,nodiratime,logbufs=8 I tried playing with the log size and logbufs, but to no avail. I would be thankful if you could give me some pointers as I have spent the last 3 weeks fiddling with filesystem etc..
