Well, it should be if we were comparing apples with apples, but we're
not. There's nothing particularly speedy about the x86 architecture.
The only reason those guys get any performance at all out of their
systems is the amazing process technology which results in huge clock
rates. It's still a mid-1970s processor architecture.

Not entirely surprising. :-) This is precisely why UltraSPARCs do
all the heavy lifting on my networks. Well, that and the reliability.
