Couple of things.
You should determine what process takes most of the time, run 'top'
in linux with 1 sec update cycle, then use web-cyradm and find out
what process lives longer, I'd bet it's mysqld. Then check your mysql
settings for query cache & thread cache. After that I'd see if
memcached would do any good, but that requires hacking web-cyradm to
work with it, shouldn't be big problem if you know anything about php
though. Those are the bottlenecks I've seen with web-applications,
usually database queries take too much time and that slows everything
down. But mysql's query cache should be very quick & easy fix, try it
out.

Hi all,
I have installed Postfix+Mysql+cyrus+web-cyradm and have around 60
domains with 250 users. When I browse the accounts from any domain,
the page takes ages to load. I have a bi-proc 3GHz with 1Gb RAM,
scsi disks, Gigabyte NIC. I just don't understand why and I am
wondering if there is anything i can do to improve performance.
web-cyradm 0.5.5-CVS
postfix 2.3.3
MySQL 4.0.18
Apache 2.0.49 (prefork)
Cyrus IMAP 2.3.3
Many thanks !
