[Csync2] csync2 db asymetry

Hi all,

I already posted that topic earlier, but problem persists after
maintenance and clean up.

Because I noticed inconsitencies between databases and observed an
asymmetry in databases size I don't really appreciate, I recently
regenerated my csync2 dbs from scratch (with TIUX etc..). But, with
freshly rebuild dbs and a synchronized file system, I still have the
database size asymmetry observed earlier. csync2 databases are all
approximately 10-15% larger on master side.

#-C	or4	op1	ratio
maildir	237128704	216787968	1,09
sys	3743744	3363840	1,11
obmdocuments	5020672	4268032	1,18
dotqmail	7578624	6509568	1,16

What could be the reason of such a relatively systematic difference ?

The host name only differ that way: master is or4, slave is op1, so
string hostname difference should not be the reason. Files and file
attributes are obviously the same.

System and file system where dbs are stored are the same

If the difference has to do with compression or history, why is it
always bigger on the same side (master) and not randomly bigger one side
and also the other ?

Any clue welcome...
Any way do debug this ? How can I check if databases are really same ?
