1 swap kills interactivity and is really, really bad on linux. No matter how
2 much you stripe it. Swap is a true horror. So setting swappiness to 100 (which
3 means: keep caches alive, no matter what and swap the hell out of it) is a
4 really bad idea. In my experience it is better to have a very low swappiness
5 and let the kernel get the occasional data from disk, than to swap to the same
6 disks. Strange eh?

8 But better to wait 1.5s longer for konqueror to display a directory than to
9 have a jerky mouse and input lag because of swap. Remember: the kernel ALWAYS
10 swaps out the wrong stuff.
11 I have swappiness at 60 - and back in the 4GB days at 0. Because swap sucks so
12 much.

14 You are not required to believe that. But just google.
