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.

Please be more specific. Is this problem present on your development box with only a handful of traffic, or is the problem only occurring under high-traffic production servers? What kind of application you have? And what's the environment? LAMP server? –  Janne Pikkarainen Sep 13 '10 at 7:16
    
Question is vague, badly worded, missing a lot of detail about the problem, what you have done already to try and solve it, what the actual metrics are, what your expectations are.... –  symcbean Sep 13 '10 at 11:30

a combination of apache benchmark ab (launched in a client against the server) and sar (launched on the client at the same time) would do the trick, search for it on the internet, you'll find plenty of stuff.

Sar is Specific Absorption Rate? right? –  Vijay Shanker Sep 14 '10 at 3:34
    
On unix like systems sar is used to produce reports based on information that is collected by sadc. These can be used to help track down performance issues. –  Iain Sep 14 '10 at 7:33

I believe Apache Performance Tuning is the best place to start.

+1 because despite it generally being frowned on here I always love an RTFM answer. :) –  John Gardeniers Sep 14 '10 at 8:15
