High Cpu usage with MouseMove and MouseClick

[Jonny22]

Hi

I have a porblem with mouse move and click. If i leave the speed default or change it higher than 1, it use my cpu more 30%. Anybody know why I have this problem? What can I do to fix this ?

The simple code :

$counter = 0
while $counter < 20
MouseMove(Random(800,1700,1),Random(400,900,1))
Sleep(200)
MouseClick("left")
$counter = $counter + 1
WEnd

thanks

What speed are you talking about and what is this for?

Hi,

Welcome to the AutoIt forum

You need to do a sleep in the thread :

$counter = 0
while $counter < 20
MouseMove(Random(800,1700,1),Random(400,900,1))
Sleep(200)
MouseClick("left")
$counter = $counter + 1
Sleep(100)
WEnd

Br, FireFox.

Modify MouseMove to make the move instantly.

MouseMove(Random(800,1700,1),Random(400,900,1), 0)

I have made an other sleep but it's no help. And about change move instantly it's no good for me because it's like jump not move...

Try both and you'll see that the instant move doesn't use much CPU. So you have to decide: High CPU usage or "mouse jump".

Out of curiosity: What do you need this for?

Just wanted to have a script without Random to get reproducable results.

$counter = 0
While $counter < 20
    If Mod($counter, 2) = 0 Then
        $i = MouseMove(10, 10)
     Else
        $i = MouseMove(700, 700)
     EndIf
     Sleep(200)
    ;MouseClick("left")
     $counter = $counter + 1
WEnd

Surprisingly I now can't reproduce the high CPU consumption. My bad, parameter 3 of MouseMove was set to 1 (fast movement).

I'm running Windows 7 64 bit on a VM machine.

I know instant move is using less CPU but I need to slow it down. I thought there is an other way , because I have got a C++ application from my friend and it does this job with low Cpu usage.

I ran the script from the first post and my CPU usage never went above 0-1%, and this is on my nearly 5 year old Win7 PC.

[Jonny22]

It is strange because I have sent my script to my friend to test and he had also high CPU usage.

I have windows 7 64bit Intel dual core e6700 3,2 Ghz processor.

In which environment do you run your script?

Hardware? Operating System? AutoIt version?

[ileandros]

Try compiling the script and then run it.

If its just mouseclicks or moves then its propably ur pc or the way you have written ur script.

I think your script is not the 5 lines you have above... If you CALL mousemovements or click from an other function and you DON'T call them right they will take a lot of cpu usage and even crash the script after some time.

The reproducer the OP posted gives me the high CPU too. The high CPU consumption is related to the MouseMove function.

For $counter = 1 To 20
    If Mod($counter, 2) = 0 Then
        MouseMove(10, 10)
    Else
        MouseMove(700, 700)
    EndIf
    Sleep(200)
Next

This gives me high CPU usage running compiled or from SciTe as 32 or 64 bit with AutoIt 3.3.81 or 3.3.9.4 from my Windows 7 in a VirtualBox machine. Edited October 21, 2012 by water

I am back again and my problem still have. I have tried autohotkey work fine and I load autoit functions to C++ and that also work well.

I have installed older version of autoit also (3.3.8.0) but the problem is same, to much cpu usage. Have any other idea what causes it?

my autoit code:

$counter = 0
while $counter < 5
    MouseMove(200,200,30)
        Sleep(200)
    MouseMove(600,700,30)
        Sleep(200)
    
    $counter = $counter + 1
        Sleep(100)
WEnd

My conf: windows 7 64bit Intel dual core e6700 3,2 Ghz processor, 4gb 1066 mhz memory.

I ran the latest script posted on my Win7 machine, and I was seeing the same issue. I didn't see the issue previously because I had another process running that was taking up all the CPU when it's idle (boinc) so it didn't show up at first.

It only happens when you use a delay though, and I know you stated you didn't want to use the instant move, but if it only happens when you're using MouseMove, and it stops as soon as the script idles, what's the issue?

[water]

I just tried it on my Windows 7 machine. I get the high CPU consumption as well.

I can imagine why:

If you set parameter "speed" to 0 the mouse is moved instantly and only a single operation is executed (show the mouse at the new coordinates).

If you set parameter "speed" to > 0 then a lot of trigonometric calculations have to be done to show the mouse at any location between source and target location. This soaks up the CPU.

My summary: If you want to see the mouse move to the target location you have to live with the high CPU consumption!
