We found that Sun JDK 6 outperformed JRockit 5 by a reasonable margin, but that if you compare JRockit 5 to Sun 5, JRockit was on top. However at the time we tested that Sun 1.5 did not have epoll support. I am not sure if JRockit 5 has epoll support. Lack of epoll could well be the reason for high CPU utilisation with that number of clients. RG
