My imap processes seem to all be running with a nice value of -15 (top priority). Is this usual? Not sure if this is a dovecot setting or something going on with my own system configuration somewhere.
Normally Dovecot doesn't touch processes' priorities, so they all run with whatever priority was specified for the master process when starting it.
Hi timo - thanks for this. The /usr/sbin/dovecot process itself was indeed niced to -15. Why would that be? Can dovecot specify it's own nice value upon startup?
Nope.
When you say 'specified for the master process' I'm not sure if you mean in a config somewhere.
I meant whatever/however dovecot was started. I don't know if some init.d scripts play with priorities. Or it could have just been that your shell was running with -15 when starting dovecot.
Anyway, I don't think Dovecot itself should change its priority on startup.
