Fresh copy of large maildir

Hi all,

I have some fairly large maildirs now (> 2GB) and running offlineimap 
plainly on them is quite ... slow.

So here's my question:

1. Is there some optimization for such a task (e.g. compressing bulks of 
messages) already present or would that be a completely new work?

2. Rsync usually works fine, although it naturally keeps filenames. 
Therefore I cannot simply rsync two maildirs (offlineimap will ignore 
the present messages and effectively double the size). Could offlineimap 
re-index a present folder offline?
