I have some archive mails in gzipped mboxes. I could use them with dovecot 1.x without problems. But recently I have installed dovecot 2.0.12, and they are slow. very slow.
Creating index files takes about 10 minutes for ~20M file with 560 messages for bzipped mbox, for gzipped is little better but still unusable :(
What other software, if any, was also upgraded/changed when you upgraded to Dovecot 2.0.12? Libraries? Filesystem? Daemons? What
IIRC only dovecot - I simply upgrade debian package via aptitude.
The latest Debian stable dovecot package is 1.2.15-4. If 'aptitude upgrade' pulled 2.0.12 then you are running either testing or

If you're running testing/unstable you should already know how to check this. Inotify is a kernel API. For Debian Dovecot to use
I know what is inotify, but I haven't to test it so far. :|
inotify it must be compiled with the build option 'notify=inotify'. You'll need to see the package maintainer's build script. You'll also need to look at the kernel .config used to build your kernel as inotify must be built into your kernel.
I have uninstalled debian's package
configure with --notify=inotify, and it looks that inotify exists and is used[1], make make install
then run with --8<---------------cut here---------------start------------->8--- #strace -o ~/tmp/dovecot/log -ff dovecot -c /etc/dovecot/dovecot.conf --8<---------------cut here---------------end--------------->8---
connect with mutt and select one of gzipped folders
connect with fetchmail and select another gzipped folder (with the same contents as in 5)
grepping strace logs shows that in both cases mboxes are reread regularly :( moreover there's no inotify_init (...) call by any dovecot process.
Any ideas?
[1] moreover inotifywatch works as expected.
