I am also using the plugins of wordpress

WP CACHE. normally 1500 to 2000 visitor visits my website at the same time.
Same problem occurring on my other website that also have wordpress blog but its on dedicated server of hostgator. 2500 to 3000 visitors remain on the site at the same time. How to recover this problem? I even upgraded the wordpress version but problem is still persisting. The server is apache 2.3.6. Processes list is showing something like...
