The Volano Report http://www.volano.com/report/index.html
It's a new, faster version of VolanoMark running on faster hardware, updated operating systems, and the latest Java 1.3 and 1.4 virtual machines from BEA, Blackdown, IBM, and Sun. I tested up to 10,000 connections this time. Back in 1998 I could test to only 900 connections, and most of the Java platforms couldn't even make it past 500 connections, so we've come a long way! Let me know if you see any tricks or command-line options I missed that would be helpful.
Now it's time to drop Java 1.3 and see how the "new I/O" implementations perform way beyond the 10,000 connection level on the modest Dell OptiPlex hardware we use. I'm curious to compare the message throughput at 50,000 connections on a new Hyper-Threading Pentium 4 with a gigabyte of dual-channel memory, for example.
