[Dovecot] high imap load on large folders

Hello,

i sync with imapsync from an archiopteryx-server to an dovecot-server, for
testing until now.
The dovecot is inside an VM. storage for mail is on an nfs-share, indexes
are local.
What i now see, is, on large folder( 58000 messages and more) the load 
on the imap-process
is very high, and slowdown the transferprocess.
Is there something, I can do. Whats cause the high load ind the 
imap-process.

Here are the configuration, and below, a partial strace
