Differences in network between 6.4 and 7.3

[Alex Huth]

Hello!

After a upgrade from 6.4 to 7.3 it seems that we have problems with the
network. On the host are running several webserver and a squid, build
with openpkg. I have installed the compat package to be sure that there
are no problems with the libraries after the upgrade.

Now we have network latency problems, with a wiki and bugzilla running
on a DomU (seperate SLES 11 host). Also we get lots of open connection
on another DomU where a webcontainer is running.
In this case we have unreassembled packages and lots of dup ACK in the
traffic.

Any idea what to do and where to search for the problem?

Thanks in advance

Alex
