- If you're using OpenWindows 3.0 then the recommended swap size is 2.5
- times physical memory. We get buy with 2 times and performance seems to be
- just fine.

- One thing you might consider when having to add aditional swap space is to
- try swapping on more than one device. This will avoid having to reformat
- your hard disk when adding memory and improve swap i/o throughput. See
- the man page on "swapon" for details on how to implement this.
