Holy smokes, look at the performance of JGroups 2.5 !
This entry actually started out with a title like "JGroups 2.5 CR-1 released". Hmm, very boring ! Scrapped that, as I really wanted to talk about the 2.5 CR-1 performance, which is GREAT!
I mean, don't get me wrong, 2.5 has some cool features, like the concurrent stack, out-of-band messages, better thread naming and so on. But I'll discuss those when I release 2.5 GA.
Okay, so I ran the perf.Test which ships with JGroups, so anyone can try it out, in our Atlanta lab. The hardware and software setup is described here. I ran the tests with the standard tcp.xml config file from JGroups/conf with only slight modifications, e.g. a bigger thread pool. So far, while JGroups has been quite good at 100Mbps ethernet, and has been able to reach ~ 11MB/sec/node, it has never been able to utilize the bandwidth available to 1GB switched ethernet (ca 125MB/sec). But this changed dramatically with 2.5 and the concurrent stack. I ran only selected tests, and will discuss performance in more details later. Look at the numbers I got:- 6 nodes, 5M 5K messages with tcp.xml, 500 threads/sender: 15'105 msgs/sec/node, throughput=75.52MB/sec/node
- 6 nodes, 5M 5K messages with tcp.xml: 17'832 msgs/sec/node, throughput=89.16MB/sec
- 8 nodes, 5M 1K messages with tcp.xml: 63'513 msgs/sec/node, throughput=63.51MB/sec
- 8 nodes, 5M 5K messages with tcp.xml: 16'600 msgs/sec/node, throughput=83MB/sec
