Can you times 10 the loop length, and make sure there really is a difference? Which ones? The i++ loop results in the following: The i = i + 1 version is somewhat shorter: I can't replicate this behavior all three appear to be about the same time for me. The Reference manual says that inc generates optimized code, so it should be quicker than the other variant, inc(i,x) works as well and adds x to i. BTW you might try to test it by letting the computer count and stop the time by calls to the GetTime procedure (DOS Unit). Stack Overflow for Teams is a private, secure spot for you and Test this code in Flash: var i:int = 0; for (var j:int = 0; j < 5000000; j++) { i=i+1; }// use about 300ms.

We will take a look at The compiler instructions used, Typecasting along with the operations and benchmarking the two operations. Etymology 1 From (etyl) fast, from (etyl) ; see it for cognates and further etymology.The development of “rapid” from an original sense of “secure” apparently happened first in the adverb and then transferred to the adjective; compare (hard) in expressions like “to run hard”.The original sense of “secure, firm” is now slightly archaic, but retained in the related .

Based on my experience, i := i + 1 is faster on Intel 486 and Pentium machines, whereas inc(i) is faster on Intel 386 and Cyrix 486 machines. > > -- > > Dirk Manders (d...@via.nl), > >  Greetingz from Neerkant, Holland (it's probable raining here.... as usual), mov ax, [someaddr] inc ax mov [someaddr], ax. In article , >  i := i + 1;  (= 3 clocks) >    mov  ax,[0050] >    inc  ax >    mov  [0050],ax, >  inc (i);  (= 1 clock) >    inc  word ptr [0050], >  inc (i,2);  (= 1 clock) >    add  word ptr [0050],0002, >  mov  ax,[0050] >  add  ax,0002 >  mov  [0050],ax. Though I didn't check it, i := i + 2; will probably be: mov  ax,[0050]   add  ax,0002   mov  [0050],ax. – I'm in doubt here.
