It is quite possible to put the system in a state where it must reload all software from scratch since one needs to recompile and reinstall the kernel. Red Hat was contacted for technical support after it was noticed that Linux was getting such poor performance. Response was that they only provided installation support and that they did not provide any support for the Linux 2.2.2 kernel. Mindcraft posted notices on various Linux and Apache newsgroups and received no relevant responses. The various Linux and Apache knowledge bases on the Web were also searched but nothing was found that could be used to improve the performance being observed.
Some tunes require one to recompile the kernel.
The documentation on how to configure the latest Linux kernel for the best performance is very difficult to find. Researchers were unable to obtain help from various Linux community newsgroups and from Red Hat. There were no books or web sites that addressed performance tuning in a clear and concise manner. At best only bits and pieces of information from dozens of sites. The kernel source code contains comments regarding tuning and configuration were found.
