i attached 2 compression logs. This logs are from 2 short sessions with 
my test account. Unfortunately myJabber.net where i have my real account 
supports no stream compression, so i can't create a log from a 
long-living session.

But i think from this logs you can get some idea how well zlib does the 
job. The very small incoming and outgoing packets are presence packets 
(90-98% compression). In log2 I browsed some chatservers where the 
compression rate is about 20%.

you also see that the keep alive whitespaces blow up 400% with 
compression enabled ;-)

Comp	= count compressed bytes
Org	= count original bytes
TComp	= total count compressed bytes
TOrg	= total count original bytes
