You may want to tune your kernel vm parameters with sysctl. 1.6 uses a
unified buffer cache, so it might end up tossing a lot of your
processes out of memory to do file i/o. This tends to make interactive
performance bite. Playing with those numbers is key to making
interactive performance smooth on a small memory machine.
