On second thought, it looks like 2.4.2 may also exhibit the
same behaviro after a little while. Now that the machine has
been up for a half hour or so, NFS traffic has become slow on
my 2.4.2 client again. I am seeing messages like this in my
kernel log:

Apr 3 15:01:54 hagrid kernel: nfs: server tela not responding, still trying
Apr 3 15:01:54 hagrid kernel: nfs: server tela OK

The machines are *not* having any connectivity problems, at
least judging from TCP sessions I have open between them.

So it would seem that NFS performace degrades over a very
short window in 2.4.2+. It seems to fairly fly when the
machine is freshly booted, but after 30 minutes or less, the
performance is severely degraded.

Is anyone using 2.4.2+ as a NFS server/client with success?
Am I missing something?
