I would try not using pooled buffers. We have found that is more
effective particularly with JDK 1.6.
OK. Will check with that right away.

You could also try the alternative thread pool that we developed for
Qpid (see previous message I sent about it).
Yes, that's also something I want to try. Do the filters work without any probs?
Is your test creating and destroying lot of connections? Or is your
test setting up connections, then just pumping data through them?
The memory utilization problem is seen when connections have not
started closing. New connections are made at the rate of 4/sec and
existing connections are generating requests.
