accessing , list messsages , copy, move delete operations it must not be zlib related, that was a guess there are two other patches only maildir related might be a better guess http://hg.dovecot.org/dovecot-2.1/rev/7389ff729d2e http://hg.dovecot.org/dovecot-2.1/rev/4c05b9447a10 other patches dont look related to me, however i use a lot of other plugins which might also involved sorry not easy to measure , but performance here is def better with 2.1.15 , same client setup, no special failures about that in debug logs > Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Axel von der Ohe, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein
