Lines: 21 Summary: A Mac is 2.3 times slower References: Xpath: icdoc ivax I recently ran the following machine code program on both a Mac and a SUN II. The reason was to evaluate how fast my system would run on the SUN II start: lea test,a0 move.l #100,d0 @1 move.l #100000,d1 ;thats one hundred thousand. @2 move.l (a0),d2 move.l d2,d2 subq.l #1,d1 bne.s @2 subq.l #1,d0 bne.s @1 rts ;end of test I got a performance ratio of 2.3 (the SUN is faster) when I ran this test and the mouse was completely quite. The ratio went up to 2.4 when I moved the mouse around whilst the test was running on the Mac. The ratio comes from counting ticks on the mac, and system time ticks on the SUN.
