How much swapspace does one realyy need?

There is a lot of discussion going on and on about swap space.

I just found this:

Especially those installing for the first time.

Very interesting -- thanks Fintan!

This is significant:

A note about Desktop and Laptop

If you are going to suspend to disk, then you need swap space more than actual RAM. For example, my laptop has 1GB RAM and swap is setup to 2GB. This only applies to Laptop or desktop but not to servers.

On my desktop system, which has 4G of memory, I have been using a 1.6G swap space for about 6 months now, with no issues. Since I have plenty of memory, I use Suspend to RAM instead of Suspend to Disk, using kpowersave, and it works great and reduces startup time, too.

And you may want to reset your swapiness value. Default is 60, which is a good value for a server, but for a desktop a lower value might be better. I have mine set to 10.
