So how do you fix the problem, other than by adding many gigabytes of RAM to the server? One easy way to get around this limitation is to either reduce the KeepAliveTimeout to a mere second or two, or else to simply turn KeepAlive off completely. I have found that turning it down to 2 seconds seems to give the client enough time to request all of the files needed for a page without having to open multiple connections,

This article looks into getting maximum performance out of Apache with the existing hardware resources, specifically on the Linux systems. Of course, it is assumed that there is enough hardware resources, especially enough RAM that the server isn't swapping frequently. First two sections look into various Compile-Time and Run-Time configuration options. Run-Time section assumes that Apache is compiled with prefork MPM. HTTP compression and caching is discussed next. Finally, using separate servers for serving static and dynamic contents are being discussed. Basic knowledge of compiling and configuring Apache, and Linux are assumed.
