IT Headquarters is pleased to present this performance tuning guide for running Xoops on IIS 6. The results I obtained through creating this article suprised even myself with PHP script execution times improved by over 1000%, and page loading times improved by over 630%!!. There were many other discoveries I found along the way, and all this on a server with very modest hardware specifications. This guide shows the major steps you need to take to get the most from your server hardware so it can take massive amounts of traffic in its stride. Who knows, it might even be able to take a slashdotting should one every come your way !
