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.

Disable this during the sync, it'll add delays. And if you don't have more than one NFS client accessing the same mailbox at the same time, you don't need it anyway.
Also see if maildir_very_dirty_syncs=yes helps.

strace -tt would have been better, it would have shown timestamps then too. But it didn't look like it did anything unexpected.
