How to analyse performance issue on apache web server?

My web application is suffering form the performance issues. like delay in response and all,

I would like you to give me some pointer where I can learn about analyzing performance issues on apache server.

Update : One good suggestion I am going to implement is to add caching support for web server. I am going to do that. Will see what performance improves after this support is added.

Thanks.
