How to investigate bottlenecks

I am using RichFaces 4.2.2.Final.

My application's performance will decrease gradually.

I want to investigate bottlenecks.

How can I find bottlenecks?

I tried to set the logging level to Trace.

But I can not find bottlenecks.

Hi burton, what does it mean "My application's performance will decrease gradually."?

Does it mean the performance is okay on the start of the application but in time, the performance is getting worse?

Which performance you refer to? Number of requests per time-unit which RichFaces application can handle?

Thank you for your reply.

Yes. That's right.

The reaction of WebUI becomes slow.
For example, my application has some popup panels on page.
Showing these popup panels will be slow gradually.

My application is composed of a single page.
Therefore page has many components.
I think it may be the cause.
I want to know whether a cause is in a client side or server side.
