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 !?!?
