Hi,
i have 2 dovecot imap server running on solaris 10
The primary server with dovecot 1.0.alpha4 is running with best performance on Sun Sparc E4k5 with 8x 450MHz
The secondary with rc10 has ugly performanceproblems on Sun E450 wth 4x 450MHz. Every new imap process takes permanent 25% cpu usage
List the folder and fetch message are both slowy!
Both servers are configred with ldap backend
preventive i deleted for rc10 the complet index and controlfiles, because the spooldir is a sync from the masterserver with dovecot alpha4. I thought its a little bit slowy because of my 30.000 mails.
the indexfiles are created now, but the still ugly slow ....
For debugging i compiled rc10 again --with-debug=yes and start dovecot with solaris truss
truss tells nothing to explain this behavor logentrys from dovecot has this warnings:
-->
dovecot: Oct 18 14:51:47 Warning: IMAP(saar): Growing pool 'storage' with: 1024 dovecot: Oct 18 14:51:47 Info: IMAP(saar): dirsize quota limit = 750000kB dovecot: Oct 18 14:51:47 Warning: IMAP(saar): Growing data stack with: 32768 dovecot: Oct 18 14:51:47 Warning: IMAP(saar): Growing data stack with: 65536 dovecot: Oct 18 14:51:48 Warning: IMAP(saar): Growing data stack with: 131072 dovecot: Oct 18 14:51:48 Warning: IMAP(saar): Growing pool 'uidlist record_pool' with: 32768
<--
also i compiled rc10 --with-notify=none, no result
to ensure it isn´t the solaris system, i compiled alpha4. Result: good performance
Any ideas?
Cheers
