I have a phpFox sociel networking website with 15,000 members. The site is located on two VPS's: 1st VPS: All php scripts, images, html files 2nd MySQL database This arragement was done to allocate more processing power as the site was running slow. Now after hitting the 15,000 mark, the site is slow again and probably needs to be: 1) optimized or 2) load balanced on a 3rd VPS or 3) cached or 4) all of the above If you bid on this project, it means that you are going to effectively increase the speed of the website by at least 3x . We can time a certain page load time before you start working, and then time it again after the work is done to find out whether the speed has improved. If you need any more information, please post to PMB. Good luck!
