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
