Hi,
I am using tomcat as my server and there is about 130 servlet in my web
application.
I want to increase the number of concurrent users in my server. Currently it
supports about 200 concurrent requests (tested by JMETER).
I tried tuning the number of threads (maxThreads) in tomcat's thread pool in
server.xml. But I found no change. It still can't serve more than 200
concurrent requests. I am not an expert in server side technologies.
Please help me in this regards.
This is my server environment and tomcat's server.xml:
