I'm running a Centos 5.4 x64 Server with Raid0 HDDs and XFS.
I did some performance tweaking according to  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
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..
