| Some of the most notable performance improvements for Linux can be accomplished via system control (sysctl) in /proc/sys. Unlike most other areas of /proc under Linux, sysctl variables are typically writable, and are used to adjust the running kernel rather than simply monitor currently running processes and system information. In this article, I'll walk you through several areas of sysctl that can result in large performance improvements. While certainly not a definitive work, this article should provide the foundation needed for further research and experimentation with Linux sysctl. |
