Increasing performance by tuning swappiness

[Henrique Ser]

I beg to differ. I have both a B2 and a B4, and running 500+ builds 
(currently 595) in the B4 goes as smoothly as expected, but the B2 just 
drags itself around. This was obviously primarily due to lack of memory, 
so I'm swapping off a 512MB external flash drive and it's still slower 
than the B4, obviously, but it works pretty fluidly, so there is a major 
difference in the B2 using swap, I can assure you of that.
