Hmm, I did warn that I was going to be rushed.

More accurately, that's what the absence of a bottleneck is.

That's "K6/233", AMD's predecessor to the Athlon. Pretty much the last
x86 CPU to run super-cool -- though Intel's Pentium M "mobile" series is
reported to be respectable.
It's a measure of just how much CPU power (usually) doesn't matter in
(at least conservative-type) typical Linux deployments that the 1997-era
K6 box is _still_ pretty zippy, either functioning as pretty much any
type or server or running lightweight X11 desktop environments such as
Window Maker. Of course, if I tried to animation-rendering work, or KDE
with all the chrome-effects enabled, it'd be toast.
 In all aspects other than floating-point performance, it was the
equal of the PPro and Pentium II CPUs of the same era -- and cost a
great deal less, _and_ ran a lot cooler.
