check remote mail, high CPU load
I have recently installed a licensed version of GMail 2.2.0 and have it setup using mysql, shared pop3 from a qmail catchall account. I only have 20 users registered so far, as I just installed it a few days ago.
I have a user account myself and setup a remote pop account that reads off a qmail pop on the same server. The problem is if I have emails when I check it it seems to go fast, then stop halfway and pause for 3 minutes, then continue a bit, pause then finish. This takes about 5 minutes to get 50 emails. If I telnet in and open TOP I can see the webmail.cgi process is maxed out at 99.9% CPU load most if the time during the five minutes of incomming remote mail check. The server is under no other stress from other normal processes, the average load is 0.16, but remote mail incoming check makes the load average shoot over 1.20 after just a few minutes. I just checked mail and it took over 3 minutes at 99% cpu to tell me I had two emails. The two emails were text, no atachments. If I have no mail it checks in less than one second.
I installed the spamassin plugin and thought maybe that was slowing it down, so I uninstalled the plugin and there was no noticeable change in performance. I reinstalled spamassassin plugin.
Thanks for any help.
