Along the same lines of freeing up memory:<p>A couple days ago I tried changing the swappyness setting of the vm on a box that I have a few servers on:<p>echo 100 > /proc/sys/vm/swappiness<p>Suddenly, a ton of unused memory that my apps had been eating up was forced into swap and my apps have been way faster since then. Anyone had similar results? Would this be something that shared hosting providers with severe memory limitations should consider doing?
