Just did a quick, non-scientific benchmark of P21 using the 3d graphics
stuff I've written. I compared P21 running Jeff Fox's P21Forth with
IBM PCs running LMI's UR/Forth386. Since UR/Forth has line drawing
routines in assembly, and P21Forth's are in high-level Forth, I did the
benchmarking without drawing the lines. So, this is a measure of integer
math speed, using a "real world" application.

P21/6Volts 30
386DX20 35
I was quite surprised at how well P21 did. P21Forth is not as tweaked as
UR/Forth, with many words still in high-level Forth. When Jeff has time
to CODE the line drawing routines, I'll revisit this benchmark.
