Here are some speed comparisons of Misty Beach Forth
versus some other Forth implementations. Note that Misty
Beach Forth has several reported times because I ran it under several
environments. The best result is running under Symantec Cafe 1.51
with version 2.00b19 of their JIT. Using this environment, Misty Beach
Forth is as fast as the native x86 Jax Forth.
Obviously, this is a far from complete benchmark of Forth implementation
performance. I have some pointers to better benchmarks, but haven't downloaded
and run them yet. As I find and run better benchmarks, I'll add them here.
If you know of any, I'd appreciate an e-mail.

I'm using a variation of a benchmark posted by Bernie Mentink. See
F21 and F*F
by Jeff Fox for a discussion and results from other Forths. Note that
the original benchmark only loops to 1000 in both loops, so the numbers
reported by Jeff Fox must be multiplied by 100 to compare them to these.
: INNER 10000 0 DO 34 DROP LOOP ;
: BENCH 10000 0 DO INNER LOOP ;

Jax4th is a GNU copylefted 32-bit Forth by Jack J Woehr. Jack provides the following
Jax4th is not an optimizing compiler targeted at professional development. The
author did not dream of providing in two hundred (200) hours of his time a freeware
Forth to compete with professional systems which required thousands of hours of
programmer time to complete.
