How to find cpu, io, memory usage of download page in web application

Question

I wrote a Java file using Jsp, servlets for which I would like to run runtime tests. I had never done this before, and I was just curious how to do it.

What I am interested to know, besides the actual timings, is how to find the processor, memory, and using io when starting the application. Your thoughts are appreciated.
