I'll take it if it's all that we have, but Quark is really weird. It's
probably Intel's last sold 32-bit-only CPU, but it wasn't used for
anything remotely performance sensitive, it's more like a 1995 CPU than
a 2010 CPU, and Intel probably sold like twenty of them. ;)

But, seriously, we don't need to go digging in the junk heap for
performance numbers. If nobody has one handy, it's just extra
justification for "we don't care".

But let's just say *THAT* instead of doing some kind of performance
theater where we pretend that like every cycle on CPUs from 2003 matters
on a 2026 kernel, and that we even cared enough to measure it.
