Has anyone here, who uses XFS fs, experiencing slow filesystem writes?
I'm seeing throughput of like 4-3MB/s instead of like previously
15-20MB/s.
I have read that there was some thing about "barriers" and I've tried
re-mounting the FS w/ "nobarriers" but the performance didn't improve.
I've alre
Hello,I just had the same problem. I switched to XFS about two weeks ago, and all I've heard out of my hard drive since then is churning and grinding. Untarring large files is multitudes slower, even a simple emerge --sync takes extra time. Booting was also much slower. I never measured through

Mine is set at 3000 by default, why is yours set at 500?

There are a number of things you can do to speed up XFS.

Try this :)

get good performance when eg: copying a file from the XFS partition to

These are two articles that indeed led me to believe that XFS was the
way to go - and here, I'm also experiencing some dreadful performance -
tar/untar performance specifically.

Can you define "dreadful"? Are you seeing the same results (fast

You are correct, sir. Read times move at a nice clip - but untar/writes
seem to get cut almost in half. Just an observation - as I do not have
any solid data analysis atm - just a matter of scratching my skull
whilst I listen to what seems to be some serious HD churning.

Hmm, I missed this before. "nobarrier" should be showing up here. Try:
mount /home -o remount,nobarrier

nobarrier went into 2.6.17 I believe (kernel related change) and was
discussed on the XFS mailing list.
