I would be interested to know if its the python part of the Bridgeserver
or the quickbridges that are causing the sluggishness.
I guess you can tell this by looking to see if the quickbridges are
I have always been a bit worried by the load caused by quickbridge.
A quickbridge with no clients should not use any resources as the process
blocks in a select call but if you are running multiple active bridges at
the same time then you are going to get a lot of process thrashing as the
CPU switches between the bridges.
Actually QB is written so a single process can bridge multiple streams at
the same which might aleviate the problem a bit. It would probably not be
too hard to write a version of QB which sets up a session on a single
forwarding process rather than forwarding the packets directly.
