I've been seeing quite a bit of page in/page out going on, and have been looking
around.
With the 2.4 kernel, when would one expect to see swap usage? I'm assuming the 2.4
memory works a bit like Solaris where one should expect to see physical memory usage
relatively high, and that's a good/normal thing, but I don't see any swap utilization
at all, which concerns me. I may have misconfigured something...
