If anything it should be the other way around. No idea I'm afraid. I've just clocked 42.86M on an Athlon/1333 though ;-) At the other end of the scale a P5/90 manages 2.91M ops/sec. Taken together (and with the K6/200 time) that is something fairly close to linear scaling with clock speed on x86 machines although the K6/200 seems to be beating the odds a little.

Of course, since time_i is one of the opcodes looped, it probably brings the numbers down. That's actually what test.pasm tests. :) I just checked in a new version that prints labels. FWIW, my 600MHz Alpha clocks in at around 23M ops/sec. Nyah! ;-P Dan --it's like this--- Dan Sugalski even samurai [EMAIL PROTECTED] have teddy bears and even teddy bears get drunk

Yeah, I realized that _as soon as I posted it_. Doh! Heheh, for the longest time I thought test.pasm just did stuff for a while. Anyway, it started out as an implementation of the bogomips.c program and slowly became this. FWIW, my 600MHz Alpha clocks in at around 23M ops/sec. Nyah! ;-P I get 10M ops/sec on the Athlon 700 using test.pasm. time_i is a killer, especially judging by the difference in cpu usage (test.pasm is nearly 100% user, and mine is 75/25 user/system) The 866 machine gets 15M. Maybe when/if I get my 1.26GHz machine at work I'll be able to match you :) Brian Dan --it's like this--- Dan Sugalski even samurai [EMAIL PROTECTED] have teddy bears and even teddy bears get drunk
