Apache 2.0 Beats IIS at Its Own Game

IIS takes another hit: "eWEEK Labs compared the performance of Apache 2.0 and Microsoft Corp.'s Internet Information Services 5.0, both running on Windows 2000 Advanced Server. Apache kept pace with IIS during the entire test, which means that sites that move from IIS to Apache 2.0 on Windows won't have to worry about taking a performance hit."
