Understanding function execution time

[Ritt]

Hello, I have a question about the execution of what I believe are called functions (WinActivate/WinClose/Run/and so forth). What determines the amount of time it will take the specified command to finish and move on to the next. Is there a way to decrease this time?

For example:

Run("notepad.exe")
WinWait("[CLASS:Notepad]")
$W1hndl = Wingethandle("[CLASS:Notepad]")
Winsettitle($W1hndl,'',"Window 1")
ConsoleWrite("Window Title Renamed." & @CRLF)
Send("!{Tab}") ;unfocus
$begin = TimerInit()
WinActivate($W1hndl)
Local $dif = TimerDiff($begin)
WinClose($W1hndl)
MsgBox(0, "Time Difference", $dif)

When I run this, It takes about 250ms, however if the send alt-tab is commented out it takes about 500ms. It doesn't make sense to me, why would it take longer to give focus to a window that already has it? Also 250ms to seems like a lot of time to move from one function to the next. Am I wrong? Is this normal, and theres no faster way to do this?

On a side note, I'm just trying to understand the capabilities and limitations of autoit. It's not that I need a window to activate and move on within 10ms.

Thank you for your time.

You can try removing the winactive line. The window doesn't need to be active to close it. Least I don't believe so.

Send("!{Tab}") ;unfocus  <--- comment out for different timing / If removed window is active and it will take 500ms to refocus/ if kept the window becomes inactive will take 250ms to refocus

$begin = TimerInit() ;Timer is starting
WinActivate($W1hndl)    ;Refocus notepad window
Local $dif = TimerDiff($begin) ;Timer has ended
WinClose($W1hndl)

Winactive is the only function being timed in this situation. I just added the winclose so you wouldn't have to do it manually

use this:

Opt("WinWaitDelay",10)

Ok cool. My other best guess would be that youre limited by your computer hardware. A rig with the biggest and baddest processor might give different results than your everyday run of the mill pc. It may give you a faster result if the script is compiled.

Disable Aero and Enable Classic Windows Them.

Remember:

Install Driver for VGA.

Change - increace the Refresh Rate in Monitor and VGA driver.

Remove any wallpaper from your desktop.
