During norml operation this morning we're seeing a significantly increased load on the IMAP server (factor 5, from 5 to 25).
Does dovecot need to rebuild index files or perform other IO intensive operations after the upgrade?
We're using Maildir
Our monitoring shows increased "system" time. We're runnign fewer processes, the IO rate ist identical to yesterday, memory usage is identical.
I found the reason: My excessive number of ca-certificates!
dovecot-lda invoke doveconf, which in turn needs a whooping 1.2s wallclock time to parse the config!
I pruned the ca-certificates file and removed ALL ca-certificates but the ones that belong to the certificate chain for postamt.charite.de
