Thanks for reading this. We got an issue with our web server, we have a rather large website, with 500-800 concurrent users at any time, we use a dedicated server to host it, we use prefork to increase the speed of the Apache, but recently we experience a problem where our website takes longer then usual to load, tested it out in pingdom tools shows that the "wait" time it the main factor.
Also attached a screen shot of the "top" command.
Any help and tips will be highly appreciated.
