[Bug 43484] Re: poor disk performance during heavy io

[J. Bruce Fields]

I don't recall ever finding a kernel that this was *not* a problem with,
so I suspect the above-referenced discussion is correct, and that this
is to some degree inherent to the ext3 design.

But, to give a specific example, I can reproduce the problem with
whatever's in current Gutsy; uname -a says:

        Linux pig 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008
i686 GNU/Linux

I also trying changing the mount options (adding noatime, nodiratime,
and data=writeback), ran a compile and did some file editing, and
confirmed that the worst of the latency is gone.
