Reduce CPU Load

[Emiel Wieldraaijer 9]

Hi All,

i always used the following in my while/wend loop to reduce the amount op cpu usage the program uses.. when just displaying the GUI

but after the last release this option will not reduce the cpu load anymore.. has something changed or is this not the correct way

Switch $msg
   Case - 3
      ExitLoop
   Case - 100 To 0
     ContinueLoop
EndSwitch

Thnx

Emiel

Where is the full loop's code? Are you using GUIGetMsg() in the loop? Are you using OnEventMode? Not enough info to say here but looks like you did a cheesy fix that relied logic overhead to slow the loop down. The newer versions are more optimized so I guess this doesn't slow them down as much anymore. Can't really say though because like I said we don't have enough information.

Using even a short Sleep(250) inside that loop would reduce your cpu usage.

@The Kandie Man

$traymsg = TrayGetMsg()
$msg = GUIGetMsg()
  Switch $msg
    Case - 3
      ExitLoop
   Case - 100 To 0
     ContinueLoop
 EndSwitch
 Select
  Case $msg = 0
    ; and the rest

@weaponx

i don't like this option .. because the buttons will respond slower

What are you trying to do with all these Switches and Case statements? I don't see you using control id variables to detect if any buttons are pressed with those case statements. Can you show your entire script so that we may understand what it is that the script is doing?

@The Kandie Man

thnx for your help, i'll look futher .. because i found

Switch $msg

Case - 3

ExitLoop

Case - 100 To 0

ContinueLoop

EndSwitch

on this forum .. some people say it reduces cpu load

i'll not post 6000 lines of code .. which are not relevant to my question

Thnx

I just use a sleep(10) in all indefinite loops, reduces cpu load by a good 90%. And i don't think they'll notice a ~10 ms delay.

My two cents.

EDIT: after smoke's post, just wanted to point out i don't just mean this for GUI loops, i mean 'most any WHILE 1 or while true etc loop.

GUIGetMsg() is all you need, you won't see any difference in CPU usage if you've coded correctly.

GUIGetMsg() already has a "built-in"10 ms delay.

Better not put an extra sleep() in the loop because that could cause GUI's not responding....

You are correct Jos i noticed it also..

but with 3.2.5.0 with the following code in the While/Wend loop

$traymsg = TrayGetMsg()

$msg = GUIGetMsg()

The next line causes the CPU usage when added for different languages

[EDIT]

If BitAND(_IsPressed("12"), _IsPressed("58")) And WinActive("GUIName") And $Language = "UK" Then Terminate()

If BitAND(_IsPressed("12"), _IsPressed("58")) And WinActive("GUIName") And $Language = "EN" Then Terminate()

Switch $msg

Case - 3

ExitLoop

Case - 100 To 0

ContinueLoop

EndSwitch

Select

Case $msg = 0

; and the rest

will reduce the CPU load of the GUI more info http://www.autoitscript.com/forum/index.ph...9&hl=Switch

Run your GUI in GuiOnEventMode. Your script can get all kinds of useful work done, and not be tied to the GuiGetMsg() loop.

@PsaltyDS

maybe that will be the solution
