Hi Connie,
I know this falls in the obvious category and you probably already checked
this, but what log level are you using? (/etc/syslog.conf)
At debug, we have found that at our moderate load (300 simultaneous users)
on linux, the CPU usage of syslogd is very high.
What does top or (glance if you have it) show as the processes using
the CPU?
Hope this helps,
John

just upgraded to imap 2.2.10 (with sasl 2.1.10) on my 11i mail server.
I did this on a test box, but could not simulate our load (several thousand
connections, ~80000 messages delivered a day), and had no troubles. But,
of course, putting on the mail server and starting up, performance is abhorrent.
I'm running 100% cpu utilization AND memory utilization all of the time,
which make the whole system sluggish and the users grumpy. All my fault,
and I need to fix it yesterday.
I have a pretty basic system--same
as can be to my old 2.0.16 one that ran like a dream.Does
anyone have any ideas for me--here is configure script:#

made changes to maxchild, prefork to try to improve perf.By
the way, it takes almost two hours to finish ctl_cyrusdb -r, and it seems

split second. #
