Optimum sleep time

[Achilles]

Since I use GuiOnEvent mode I often have loops that look like this:

While 1 
Sleep(2000) 
WEnd

I was just wondering if there was a sleep time that would produce less CPU usage... I know lower sleep times cause high CPU usage but do large ones (such as 2000) change anything?

I actually tried tweaking the value and found Sleep(20) was enough to free up the CPU. Didn't see much improvement from going higher. Nothing to stop you from testing it yourself to see if it makes any difference. Post your results when you get 'em.

Any idea how to test it?

I started to try by doing this:

While 1 
Sleep(10)
WEnd

But that already registered in the task manager as 0% CPU usage...

Try it like this, and then uncomment the sleep:

HotKeySet("{ESC}", "_Quit")
While 1
    ; Sleep(20)
WEnd
Func _Quit()
    Exit
EndFunc

Like I said before, longer times are not really necessary.

I usually use at least a sleep(1000). You want it to be as long as possible if you aren't using the loop because you are using GUIOnEvent mode. The less the processor has to do, the better. Each time it loops it is using a miniscule amount of processing power, however, over time that can add up. Since it doesn't matter, just give the processor a break and let it take a nap.
