You're kidding, right?
Dear raj.amalw, please provide the URL to your site.
While you're at it, a few other details would be helpful, also, e.g. OS; webserver you're using; have you implemented any caching; are you using a CDN, etc., etc.

Here's a good tutorial to start with: How To Install Wordpress, Nginx, PHP, and Varnish on Ubuntu 12.04.

Varnish is an HTTP accelerator and a useful tool for speeding up a server, especially during a times when there is high traffic to a site. It works by redirecting visitors to static pages whenever possible and only drawing on the server itself if there is a need for an active process. This tutorial covers installing wordpress on a LEMP stack (with nginx instead of apache), and then installing varnish.
It depends on many factors such as your Wordpress instance's version, how many plugins you have installed, how heavy your theme is, etc.

Take a look at Pablo's link above, setting up Varnish should make your Wordpress site fly ;)
