That's pretty impressive (never saw x86 with this exit rate) but it's
more than 1000 times slower than the hardware, assuming 1 fpu IPC (and

will slow to a crawl.
Measuring a typical Gekko application, I get about 200k-250k of fpu
(incl. paired singles) instructions per second.
Virtualized, yes? What's the rate on bare metal?
Emulated. I can't measure anything on bare metal.
Well, then, the rate may be low due to virtualization overhead. Any way
to compare absolute performance?
