This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Can anybody please suggest me if Tomcat web server is enough for a web-app (JSP/Servlets) that has at least 300 concurrent users? If not, can you suggest me which of the commercially available java-enabled web servers (esp. with Servlet Containers but without EJB-support) can replace Tomcat and why?
I would appreciate, if you can let me know the comparison of standard web servers along with few parameters such as Performance, Concurrent Connections, Cost-effectiveness and so on.

I have the same concern as Rao. How many concurrent users are considered "moderate"?

"concurrent users" is really not the problem since servlets don't care how many people have a browser "pointed" at your server. The important figure is response speed under load of X requests handled per second. I have done load testing using fake loads created with HttpClient and also monitored real application response time histograms for servlet generated mock exams that do a lot of object creation and manipulation. With fairly cheap hardware, more than 50 requests per second would see a slowdown.
Searching for benchmarks, I turned up this recent article. in which Tomcat seems to show up well. Bill
