I did some debugging with strace, too. It's about 22MB only for running the
lsub command !?
Run it with strace -tt and send me the output compressed?
Ah, you have ACLs enabled. With ACLs it's looking up dovecot-acl file from each
folder before returning it. This shouldn't be necessary with LSUB I think. I
suppose some kind of an ACL cache could be a good idea some day too. And maybe
a setting not to bother looking up ACLs for mailboxes in private namespaces.
Ok, so for getting off this problem I will disable acl support.
I'll try to do something about those within a few days..
I think it would be really a good thing to optimize dovecot this way. So
you can reduce a lot of I/O.
Hopefully I can get this fix - if available-, because I am using the
Ubuntu packages !?!?
