Process: No special process was peaking. How is the logging implemented? Each imap process is logging by itself?
dovecot-lda logs directly,
OK!
with everything else it goes through "dovecot/log" process.
Interesting: 1400+ processes logging through one process... Has this changed from 1.2?
Are you logging to syslog?
yes!
Hmm. System CPU usage is about time spent in syscalls..
Exactly.
Is it doing too many tiny write()s or something?
I was thinking of this as well, because the total amount of disk IO didn't change (between 1.2 and 2.0) only the time spent in system...
.. Maybe I should strace the processes and see if something's too slow there.
