There is no such limit in Tomcat. I have just tested Tomcat with 3000 concurrent connections and saw zero errors. I did, however, need to tune my load test so I didn't hit CPU or network bottlenecks. I also tried 5000 threads but started seeing errors around 4000 concurrent connections - I didn't look into why but I suspect I hit an OS limit. > it was using two jmeter > server to "attack" single tomcat.

You have two choices: - buy better hardware - tune your application Keep in mind that concurrent connections may not be the performance figure you really care about. Is response time is low, you could, for example, serve 200 req/s with only 20 connections. As a guide, the upper limit on requests per second for 6.0.20 on a quad-core 2.2GHz machine is more than 6000 req/s. Here CPU is the limiting factor and it I can hit that with less than 10 threads.
