The best performance I found for Solaris, was lots of memory being used for
processes, some disk access and some swapping going on. Linux would
basically grind to a halt on the same hardware, Solaris would not, even on
a dual 300Mhz or 400Mhz E250. And that was a real-world example of stuff
going on. Nowadays with RAM being so cheap, it is less of a use-case than
