Much difference between netperf results on every run
Hi all,
the throughput measured by netperf differs from time to time. The
changeset was xen-unstable.hg C/S 11760. This is observed when I
executed a netperf on DomU connecting to a netserver on Dom0 in the
same box. The observed throughput was between 185Mbps to 3854Mbps. I
have never seen such a difference on ia64.
Regards,
Hiroya

random cpu spikes, EBADF errors
In May I had problem with mongrels suddenly consuming huge cpu resources for
a minute or two and then returning to normal (load average spikes up
to 3.8and then back down to a regular
0.2 over the course of 5 minutes, then again 1/2 hour later. or 4 hours
later, no predictable rhythm).
I posted to Litespeed forums because I thought the problem was there but
didn''t get far. And a week
