How it works
The sysctl command lets you directly access kernel parameters. By default, most distributions optimize these parameters for a normal workstation.
If your system has lots of memory, you can improve performance by increasing the amount of memory devoted to buffers. If it's short on memory, you may want to shrink these. If the system is a server, you may want to keep tasks resident longer than you would for a single-user workstation.
