It is kind of interesting, but I never noticed much difference from the
default value (thats 60, by the way) until I set swappiness to 0.
The difference between 10 and 60 is barely noticeable, tho. You are

I have 768MB on my laptop, and I really use it. Meaning spamd, mysql,
firefox, openoffice and some nuts and bolts.
