I've noticed that for the task of "reading a file row by row into an array" FileReadToArray is consistently slower than a FileRead + StringSplit. The following script: Results in the following output for me: And the output with switched call sequence: This surprises me, since I first assume that the native function offers more optimization possibilities than having to create an array in AutoIt via an intermediate string. So I thought that maybe FileReadToArray is more economical with memory. But again FileReadToArray seems to consume more memory than the StringSplit variant. For this I got the PeakWorkingSetSize after the call of the respective function. After FileReadToArray the Size is always higher than with StringSplit. Since this is not the case if one changes the order of the two functions (see above), one can assume that FileReadToArray actually has this difference. The difference is mostly the double file size. Which would make sense if the file is completely saved internally as a UTF-16 string. Can anyone explain to me why FileReadToArray performs so unexpectedly poor - or am I missing something?

i have a file flower.txt with the name of the flowers and there picture location and information about that kind of flower. i wana cerat a gui that will display the flower picture and it information here is the script #include <Misc.au3> #include <EditConstants.au3> #include <Constants.au3> #include <ButtonConstants.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <MsgBoxConstants.au3> #include <WindowsConstants.au3> #include <AVIConstants.au3> #include <TreeViewConstants.au3> #include <GuiComboBox.au3> #include <GuiTab.au3> #include <file.au3> #include <array.au3> Global $sfPath = 'flowers.txt' Global $aFlowers _FileReadToArray($sfPath,$aFlowers,$FRTA_NOCOUNT,'|') _ArrayColDelete($aFlowers,0) ;row 0 has no data so deleting $Form1 = GUICreate("Search Flower Name",320, 480) $input = GUICtrlCreateInput("", 60, 360, 209, 25) $idss = GUICtrlCreateButton("Search", 130, 400, 73, 65) GUISetState(@SW_SHOW) Func Searchf() Global $Fname = GUICtrlRead($input) For $iNo = 0 To UBound($aFlowers[0][0]) - 1 ; if $Fname = $aFlowers[$iNo][0] then MsgBox($MB_SYSTEMMODAL, "","Flower nfo", ""& $aFlowers[$iNo][1] &"") pic() EndIf Next EndFunc While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $nMsg = $idss Searchf() EndSwitch WEnd func pic() For $iNo = 0 To UBound($aFlowers[0][0]) - 1 GUICtrlCreatePic($aFlowers[$iNo][2], 20, 30, 280, 280) Next EndFunc here is the flower.txt file |Hibiscus|Hibiscus is a hardy perennial which grows in variety of colors, sizes and fragrances.
