Colleague returned from vacation today and gave some ideas. Today I turned off the "mail_log" and "notify" plugins and the load dropped considerably. Both plugins were used with default settings.
I left all settings unchanged and examined the machine. Load stays low, so something the way how logging is done in 2.0.x must have changed.
Load as in I/O load or CPU load?.. If CPU, which process was eating it?
CPU, specifically system (not user, not idle, not wait).
Process: No special process was peaking. How is the logging implemented? Each imap process is logging by itself?
I can't think of any good reason why mail_log would be doing anything that would cause such problems (other than maybe just logging too much stuff and causing problems because of that).
That kind of logging was on with 1.2.x, unless the defaults changed between 1.2.x and 2.0.x, it logged the same amount of data...
