Hello room..

I have our production site running on Apache/Tomcat4.0.1/mySQL/FreeBSD.We have seen some performance problem when the traffic reaches 400 users.

We are aware that,single JVM has its own limitations maybe one Tomcat instance can take upto 500 user objects.Any sensible person will think of clustering/Load balancing when traffic starts pouring in.

Is clustering possible with Tomcat as compared to weblogoc/websphere..?

If not then,whats an alternative solution.Should we recommed our client to switch to websphere instead of tomcat..?
