A few months ago somebody posted a set of C (language) benchmarks: sort, fib-numbers, seive, and a floating point exercise. I sent sort, fib and prime (with a knight's tour program that showed up here about the same time) to Gimix. They ran them on a 68010 machine that they have around and on the single board 68020 system they are preparing for sale (Late Sept?). I don't have times for the knight's tour, but here are the results for the other three: Program 68010 68020 Sort 42 Sec 10.5 Sec Fib 48 Sec 12.7 Sec Seive 4 Sec 0.9 Sec All tests used OS-9 and Microware's C compiler. The Gimix machine runs at 12.5 MHz with one wait state. The 68010 machine was a Mizar (sp?) I ran the knight's tour for a 6x6 board on my 6809 system in about 10 minutes (a 5x5 board took only about 2 seconds so I didn't try a 7x7 board). I expect to have a time for the tour on the 68020 next week. If anyone has times for other processors I'd like to hear about them. Two side issues: I understand that I'm about to be quoted in UNIX World saying that OS-9 performance is far worse than Unix's(tm :-). I did say something like that. My 6809 system is not as fast as the 780 I use. In any case, on a 68020, OS-9 evidently does NOT perform poorly. I haven't mentioned any non-Motorolla processors here. I enjoyed the 80*/68* discussion, but I'm not trying to start it again!
