Hello, I wrote a benchmark script to measure variable declarations to find out whether you should focus more on static or global variables #cs ---------------------------------------------------------------------------- AutoIt Version: 3.3.14.5 #ce ---------------------------------------------------------------------------- #Region Pre-Setting Local $iTally1 = 0 Local $iTally2 = 0 Local $iTally3 = 0 Local $iTally4 = 0 Local $iTally5 = 0 Local $iTally6 = 0 Local $iTally7 = 0 Global $GLOBALCONST1 = 1 Global $GLOBALCONST2 = 1 Global $GLOBALCONST3 = 1 Global $GLOBALCONST4 = 1 Global $GLOBALCONST5 = 1 #EndRegion Pre-Setting #Region Test Functions Func s1() Static $i = $GLOBALCONST1 Return $i EndFunc Func g2() Return $GLOBALCONST2 EndFunc Func g3() Static $i7 = "gsdgdfegbgbrwefw" Return $GLOBALCONST3 EndFunc Func g4() Static $i1 = 1 Static $i2 = "asd" Static $i3 = 234 Static $i4 = True Static $i5 = [0] Static $i6 = "hgsdg" Static $i7 = 1 Static $i8 = 1 Static $i9 = 1 Static $i0 = 1 Return $GLOBALCONST4 EndFunc Func g5() Local $i = $GLOBALCONST5 Return $i EndFunc Func g6() Local $i = 1 Return $i EndFunc Func g7() Return 1 EndFunc #EndRegion Test Functions #Region Benchmark Loop For $i = 0 To 15 Local $tDelta = TimerInit() Do $iTally1 += s1() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally2 += g2() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally3 += g3() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally4 += g4() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally5 += g5() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally6 += g6() Until TimerDiff($tDelta) >= 1000 Local $tDelta = TimerInit() Do $iTally7 += g7() Until TimerDiff($tDelta) >= 1000 Next #EndRegion Benchmark Loop ConsoleWrite(@CRLF&"Static1: "&$iTally1&" pkt"&@CRLF&"Global2: "&$iTally2&" pkt"&@CRLF&"Global3: "&$iTally3&" pkt"&@CRLF&"Global4: "&$iTally4&" pkt"&@CRLF&"Local5: "&$iTally5&" pkt"&@CRLF&"Local6: "&$iTally6&" pkt"&@CRLF&"Hardcode7:"&$iTally7&" pkt"&@CRLF) #cs Result Static1: 10291881 pkt global to static Global2: 13977324 pkt only global Global3: 9886169 pkt global and static Global4: 2933051 pkt global and many statics Local5: 9937314 pkt global to local Local6: 10306484 pkt only local Hardcode7: 14835319 pkt no variable #ce Result: 100% no variable, hardcore value 94% only global variable use 69% only local variable use with hardcore value set 69% only static variable use with global variable value set 67% declaration of local variable with global variable value set 66% only global variable use with one static variable beside 20% only global variable use with ten static variables beside My thesis of the result: Be careful with declarations, whether local, global or static Note: in my test the global variable performance was better than the local one, but in practice the global one would lose performance due to multiple operations What is your best practice sharing data between multiple functions?

Hello, my question is based on topic about Nvda Screen reader development atThis Link Autoit GUI is totaly nice for blind users, because it's controls are mostly standart. But in cooperation with Screen Readers this guis are much slower than other guis. Do you have any idea about reason of this behaviour? Thanks a lot for any answer. Fenzik

Hi gang, I'm in a bit of a pickle here, the gist of it is that i have one "main" file with ~200k lines, and literally hundreds of other files each ranging from 1k - 100k lines. I need to go through each of the "other" files and (separately) compare them to the "main" file, and save the differences between the two (no duplicates) The issue is that each comparison (especially if the "other" file has 50+ k lines) takes over a minute each... Is there anyway to cut this time down? As far as i know im using the most optimized array difference script Here's a rough mockup of the script im currently using note: the main file has all unique lines, and the "other" files wont ever have any lines that *DO NOT* appear in the main file, if that helps #include <array.au3> #include <file.au3> global $info_file global $compare_file global $Differece $info_file = FileReadToArray("info-file(200k lines).txt") $compare_file = FileReadToArray("compare-file(100k lines).txt") $Differece = _Diff($info_file, $compare_file, 0) ; get the difference between 2 arrays, NO duplicates _ArrayDisplay($Differece) ;================================================= ; Function Name: _Diff($Set1, $Set2 [, $GetAll=0 [, $Delim=Default]]) ; Description:: Find values in $Set1 that do not occur in $Set2 ; Parameter(s): $Set1 set 1 (1D-array or delimited string) ; $Set2 set 2 (1D-array or delimited string) ; optional: $GetAll 0 - only one occurence of every difference are shown (Default) ; 1 - all differences are shown, allowing duplicates ; optional: $Delim Delimiter for strings (Default use the separator character set by Opt("GUIDataSeparatorChar") ) ; Return Value(s): Succes 1D-array of values from $Set1 that do not occur in $Set2 ; Failure -1 @error set, that was given as array, isn't 1D-array ; Note: Comparison is case-sensitive! - i.e. Number 9 is different to string '9'! ; Author(s): BugFix (bugfix@autoit.de) Modified by ParoXsitiC for Faster _Diff (Formally _GetIntersection) ;================================================= Func _Diff(ByRef $Set1, ByRef $Set2, $GetAll = 0, $Delim = Default) Local $o1 = ObjCreate("System.Collections.ArrayList") Local $o2 = ObjCreate("System.Collections.ArrayList") Local $oDiff1 = ObjCreate("System.Collections.ArrayList") Local $tmp, $i If $GetAll <> 1 Then $GetAll = 0 If $Delim = Default Then $Delim = Opt("GUIDataSeparatorChar") If Not IsArray($Set1) Then If Not StringInStr($Set1, $Delim) Then $o1.Add($Set1) Else $tmp = StringSplit($Set1, $Delim, 1) For $i = 1 To UBound($tmp) - 1 $o1.Add($tmp[$i]) Next EndIf Else If UBound($Set1, 0) > 1 Then Return SetError(1, 0, -1) For $i = 0 To UBound($Set1) - 1 $o1.Add($Set1[$i]) Next EndIf If Not IsArray($Set2) Then If Not StringInStr($Set2, $Delim) Then $o2.Add($Set2) Else $tmp = StringSplit($Set2, $Delim, 1) For $i = 1 To UBound($tmp) - 1 $o2.Add($tmp[$i]) Next EndIf Else If UBound($Set2, 0) > 1 Then Return SetError(1, 0, -1) For $i = 0 To UBound($Set2) - 1 $o2.Add($Set2[$i]) Next EndIf For $tmp In $o1 If Not $o2.Contains($tmp) And ($GetAll Or Not $oDiff1.Contains($tmp)) Then $oDiff1.Add($tmp) Next If $oDiff1.Count <= 0 Then Return 0 Local $aOut[$oDiff1.Count] $i = 0 For $tmp In $oDiff1 $aOut[$i] = $tmp $i += 1 Next Return $aOut EndFunc ;==>_Diff

In my script i check a small area (say 20x20 pixels) with looped PixelGetColor. This has worked without any real problems for months and has taken about 20ms to complete. To test my script, I'm running Photoshop and activate different layers to show different photos. This has also worked great. After a GPU replace (to the better) a week ago it worked great the first few days, but now I've come to a dead end. This is the deal: I open my .psd file and runs my script - performance is ok I switch to layer 2 and runs my script - performance is ok I switch back to layer 1 and runs my script - performance is horrible, almost 50ms. At this point it doesn't matter what I do, every use of PixelGetColor() is slow. Now, if I close Photoshop completely, reopens my .psd file and run the script again - performance is ok What could possible be the problem!? Could it be anything with the new Nvidia drivers - PhysX/hyperthreading and all that new shit (which I didnt use earlier)? After a search through the forums I've found some interesting stuff making me far from the only one having general performance issues using the PixelGetColor() function. I'm gonna take a shot using _GDIPlus_BitmapLockBits instead and see if that helps. But I wonder if there might be something more at work in my case? As mentioned, I'm using the same script as I have for months. I've tested with Photoshop again and again - same result. Also tried using Paint but then its horrible speed constantly. It's just now the problems started. Related links on the matter Setup WinXP GPU 1GB GeForce 3 GB RAM 1600x1200x32 Window Classic theme with all Performance Visual Effects turned off. AutoIt v3.3.8.1

Code snippet The aim is to enhance the performance of directory discovery part of a network drive, in particular when browsing a directory over a WAN or Cloud. I have noticed a significant (near to tenfold) performance profit by disabling Windows Explorer display pane ( Organize / layout / Details Pane ) Initially the key does not exist when the display pane is enabled (by default) In the example, I opted for deleting the key if $bDisableDetailsPane is set to true I have no clue what the other binary figures are meant for...
