Oh, actually that shouldn't be the problem. A bit strange why it would
take 0.5 secs there, but when calling via dovecot-lda it shouldn't do
this at all. You should be testing with:

doveconf -m lda

Maybe easiest if you make a copy of your config and keep deleting stuff
from it until doveconf runs fast so you can find what settings exactly
are causing it. Or is it slow even with a zero byte config file?
