The good news on my lastest commit, perftest results: Before: publish Time:20.226984000 publish Messages:500000 publish Rate:24719.5
After: publish Time:9.258069000 publish Messages:500000 publish Rate:54006.9 *Double* the throughput :) Much of the additional improvement is probably reduced heap abuse by the client, but there are probably some concurrency gains also - I'm running these tests on an 8 core box. Bad news: perftest --listen core dumps so the above is not the whole story, will fix ASAP.
