How to decrease CPU overhead?

[ZoltanE]

Are there best practices to keep AutoIt scripts

easy on the CPU?

I'm on a Q6600@2.4Ghz with Win7 and my floating toolbar

script costs a constant 5-8%.

With a sleep(100) in the main loop it gets down

to 1-2%, but I read somewhere that a sleep is not

recommended there.

Sleep is only not recommended when you are already using GUIGetMsg. If you aren't using that in the same loop, go ahead and add a sleep.

[ZoltanE]

Well, I am using GUIGetMsg().

So sleep makes the gui laggy... Hmm, I guess I'll have to

experiment with sleep times and see which value starts to cause

problems.

Zoltan, try replacing:

Toolbar_State()     ; Toggle "AlwaysOnTop" setting as required.
    Local $iMsg = GUIGetMsg() ; Check if an event has happened on the UI.

with

Local $iMsg = GUIGetMsg() ; Check if an event has happened on the UI.
    ; avoid unnecessary processing when no events ...
    If $iMsg = 0 Then ContinueLoop
    Toolbar_State()     ; Toggle "AlwaysOnTop" setting as required.

Of course this will only help if it actually is Toolbar_State() that eats your CPU

edit: not tested, don't have PS

HTH,

When using sleep, have a delay of 15. This provides no noticeable lag, and drastically reduces CPU usage. This is the lowest time that Sleep can accurately delay for on all windows platforms.

Thanks a bunch guys!

Use onevent mode if you are truly serious about reducing CPU usage.
