Making scripts run faster.

[javas]

I've already created my script and it works well; however for the purpose I designed it to do, it would be nice if I could get it to process even faster. One of the problems I've encountered is that in my program I have to use a lot of mouseclickdrag functions however, even at the fastest speed, it still seems very slow compared to the mouseclick commands. I also have a few questions about what runs faster and what doesn't.

1) Run as .au3 or .exe is there a difference in performance? is one better than the other? or does it not make a difference?

2) Does capitalization slow down the script?

3) Does extra lines or spaces slow down the script?

4) Instead of using a for loop if I just listed out everything will it go faster at running time?

5) Are there any other ways I can make my script faster? Every millisecond counts so whatever I can do please tell me. Thanks.

1. For a more complex script a compiled script should be faster.

2. No

3. No, but it's useless. However in extreme cases (like millions of extra rows) I assume you will notice some performance losses.

4. A loop should be way faster than a long list.

Remember that some loops are faster, for example For Next loop is faster than a Do Until loop.

5. You can always improve your script and make it faster, if you can post what you got it's easier to help you improve it.

Also keep in mind that AutoIt isn't optimized for speed, if you are looking for speed use ASM or C++.

What are the: ___ all about?

[Pain]

I got some things you can improve. I've used a speedtester to see what function that is fastest so I can't really tell if you will notice any different.

Replace all If ElseIf with Switch Case. For me it was 16% faster (still only some ms).

Create the Register function with a loop.

That's pretty much what I found but I havn't studied your code yet.

"extra rows" are removed during compilation. So are remark lines. I'm not sure what happens to them at runtime in an au3 file.

[javas]

Also, some other questions, can shorter variable names increase performance speed or is that also taken care of during compilation?

Which one of these codes is more efficient:

for $a = $index3 to 1 Step -1
 $simulation[$remove[$index3 - 1][0]][$remove[$index3 - 1][1]] = 0
 Next

or

while $index3 - 1 >= 0
$simulation[$remove[$index3 - 1][0]][$remove[$index3 - 1][1]] = 0
$index3 = $index3 - 1
WEnd

or is there an even better way to do this same thing more efficiently?

Shorter variable names will make your code harder to understand and thus harder to edit. Longer descriptive variable names lead to self documenting code.

Good to learn something new, didn't know that before.

@javas

Longer var names will make it slower, for example $a should be faster than $ThisIsMyTemporaryVariableWithAVerryLongNameThatIUseToStoreSomeValuesIn.

However a variable should describe what is does so using a variable with just one letter is not to recommend.

Also to make it even faster you should try to avoid variables and use numbers instead if it's possible, keep in mind that hex values is faster than decimal.

Btw I can't speedtest your code because it's not working but a For Next loop is faster than While Loop (While and Do Until is worst if you are looking for speed)

What exactly did you mean by hex values are faster than decimal? Are decimal values converted to hex when they are compared? And if that is the case would it then be more efficient to convert all my decimal values to hex in the beginning before the rest of the code runs since a large portion of my algorithm involves comparing values?

Also is there any way to condense

if $a = $b and $a = $c and $a = $d and $a = $e Then

Let's say I want to use the number 2147483647 (only to make it easy) somewhere in my script. If I would have used 0xFFFFFF instead I would see a huge improvement. For me it's more than 3x faster.

Example:

$var = 2147483647

If $var = 2147483647 Then ConsoleWrite("") ; the consolewrite is a dummy to be able messure time

$var = 0xFFFFFF

If $var = 0xFFFFFF Then ConsoleWrite("")

If you add the two examples to a loop, let's say 10k times with a TimerInit and TimerDiff you can see the difference.

As you can see I only converted my number into a hex value.

Hello i have this script and i really want to improve the speed

HotKeySet("{Space}", "Terminate")

While 1

MouseClick("left", 1110, 582, 1, 14)

MouseClick("left", 239, 490, 1, 32)

MouseClick("left", 821, 326, 2, 14)

MouseClick("left", 637, 394, 2, 25)

MouseClick("left", 462, 377, 1, 10)

MouseClick("left", 681, 397, 1, 0)

WEnd

 i was wondering what i would need to do thanks

[Bert]

In the future- please make a new thread instead of Necroposting.

[BrewManNH]

Set the last parameter to zero and the mouse click will be nearly instantaneous.

[Bert]

2nd - you have your mouse clicks in a loop with speed limiters and no way out of the loop. What are you trying to do? (the application)

[AZJIO]

Interesting topic despite Necroposting.
 

For me it's more than 3x faster.

 

Speed is identical

$z = 0

$timer1 = TimerInit()
For $i = 1 To 10000
    $z = 0xABCDF79 + 0xABCDF79
Next
$timer1 = Round(TimerDiff($timer1), 2)

$timer2 = TimerInit()
For $i = 1 To 10000
    $z = 180150137 + 180150137
Next
$timer2 = Round(TimerDiff($timer2), 2)

MsgBox(0, "timer", '$timer1 = ' & $timer1 & ' msec' & @LF & '$timer2 = ' & $timer2 & ' msec')

[mLipok]

try to use:

Opt("WinWaitDelay", 0)
Opt("MouseClickDelay", 0)
Opt("MouseClickDownDelay", 0)
Opt("MouseClickDragDelay", 0)
