And now I'm back with some other, more concrete questions, but first I'll tell 
briefly what has been done.

I decided to sort mails per year/month and then set up an automatic mechanism 
to sort within a month folder as desired. First I had to migrate a chunk of 
old mails to those perhaps over 1k directories. Note, that I set dovecot to 
:LAYOUT=fs, so I can use that mail tree with mutt in an emergency situation 
(which caused that all folders had to be created by hand on server, failure 
with kmail). But I've not finished the migration yet, because kmail is deadly 
slow. It takes some hours for it to process those folders every time kmail is 
started and it "burns" a cpu core. 

Is that nonstandard serverside mails tree format to blame? Or with maildir++ 
it'd be about just as slow?

I read, some other IMAP module/whatever is going to be ready for KMail, but is 
there sufficient reason to think, it will handle such large imap mailbox trees, 
which are in addition filesystem trees, not maildir++?
