If you ever get over 75% swap usage, your computer will probably start thrashing, which means that for what you are doing, you really do need more RAM. So swap utilization on average can give you a good indication of whether your RAM is sufficient. Currently I'm running gnome 2.8 (FC 3) on an Athlon machine with 512 MB of RAM. I have 1 GB of swap. Currently I'm using about 293 mb of RAM (the rest is in caches and buffers) and about 294 mb of swap. The reason for so much swap is that some programs are minimized right now and not being used, and as such have only a minimal working set actually resident in RAM. Here are some ridiculous numbers that will probably make you gentoo users smile and feel warm inside as you read this in mutt with evilwm as your desktop environment: Evolution is taking the most amount of total memory right now, with 192 MB total footprint. You have to remember that this takes into consideration memory-mapped mbox files (some of which are quite large). The actual resident set for this is only 31 MB. Galeon comes in second with 158 MB total, 40 MB resident. X is consuming 149 MB total, with 57 MB resident. These numbers are not real, though, since X reports all shared memory that is in use by X client apps as though it owned them. Nautilus is using 108 MB, 23 MB resident. Of course this after running everything constantly for about a month. At first, the swap isn't utilized quite as much but over time the working set is extrapolated and the swap starts getting used.
