gprof for detail, and even with simple strace timing. i.e. strace -c. if load is going up significantly, there should be one or more functions significantly fatter than the rest. you can pick either to run it on the whole group, or just attach to certain processes. (master, imap, lda, etc)
Timo and I found excessive numbers of context switches, factor 20-30. But it's unclear why the IMAP process would do/cause this.
when you run 'ps aux|grep dovecot', what seems to collect the most cpu time?
-d
