[ale] how do I increase Linux swap file size?

[jim.kinney at gmail.com (Jim Kinney)]

Swap space _really_ depends on how the system is used. A single user desktop
running web browsing and email can have swap turned of if the system has 4GB
RAM. Using a heavy memory application like extensive gimp on HUGE files with
loads of undo levels, leave the swap at 2:1 swap:RAM

For a multi-user server, swap use will be determined by the type of
application and the loading of it. A multi-purpose system running mail, web,
file servics, etc, will benefit from the swap space at around 2:1. But a
high performance solo-service web server running tomcat with multiple
multi-core cpu's will not benefit unless the web application has long-lived
caching of user state.

High performance file servers (NFS or CIFS) should have swap nearly turned
off or at the most 1:1 for caching of system . If a fileserver starts
hitting swap, the pager is about to start beeping.
