have you tried?:
- YSlow! plugin for Firebug.
- Google Site Speed plugin
- waterfall graphs in safari web inspector or opera developer tools.
where are the users that are complaining vs server location?
which http server are you using?
have you addressed any considerations for server or browser cacheing?
(btw it's likely to be slow around here during the holidays so i wouldn't expect any immediate attention.)

I have checked YSlow and Google Page Speed (in Firefox) and they do say that there are some problems related to gzipping css and js and some other but I don't think they will affect that much although I will definitely fix them in coming days.
No idea about waterfall graphs will check it out.
That's the main problem because these complains are also coming from business and SEO department and they are based on just Google's site performance tool because I haven't seen any concrete complain as to what exactly is wrong. It's the usual talk that "oh the site is slow...many users have said" but when I ask specifics then no answer.
I am using Apache on CentOS with 64 bit Intel Xeon 8 CPUs.
Yes browser caching is also something which I need to look into but no idea about server caching.

Actually taking care of those 2 things should significantly improve the performance.
You can use free web based tool like webpagetest .org to check how much percent each item will affect site load time.
Your web host should be able to guide you on server caching - for open source CMS like Wordpress there are excellent plugins available for browser/server caching

obviously this doesn't help first-time visitors with a primed cache but here's a start on configuring apache for proper browser cache control.
Cache control in .htaccess:

i've used this tool occasionally.
