Volume of metadata - squatter - in 2.5

[Marc Patermann]

Hi,

we are in the process of migrating from old cyrus imapd 2.3.16 servers 
to new with cyrus 2.5.10.

We copy whith imapsync - i.e. to benefit from single instance strore.

Now the volume of the metadata is increasing to a factor of like 7-15!
It seems squatter is taking a lot more space now.

Is this right?

one server:
new: 2,3G    /var/lib/imap/meta
old: 153M    /var/lib/imap/meta

another server:
new: 3,6G    /var/lib/imap/meta
old: 563M    /var/lib/imap/meta
