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<br>
<br>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.<br>
<br>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.<br clear="all"><br>-- <br>
