ArrayAdd ArrayPush ArrayInsert performance - (Moved)

Recommended Posts


Im new to autoit.

I have .csv file with 8 coloumns and over 7-9k rows with tab delimeter. I split this file into 2D array using

 _FileReadToArray($file, $retArray, '', @TAB).

In second column of .csv file i have digit based string, this strings is not unique:
for example: 

  • 57814510303
  • 57814510303
  • 57814510303
  • 57954184645
  • 57986498899
  • 57986498899

I want to get unique values in separate array, now im getting result using following code:

Local $retArray
_FileReadToArray($file, $retArray, '', @TAB)
Local $idArray[UBound($retArray) - 1]
For $i = 1 To UBound($retArray) - 1
   _ArrayPush($idArray, $retArray[$i][1])
$uniqueIdArray = _ArrayUnique($idArray, "", "", "", 0, "")

The script part with 

For $i = 1 To UBound($retArray) - 1
    _ArrayPush($korobIdArray, $retArray[$i][1])

takes over 52 seconds for 7500 entries.
May be i should use another function instead _ArrayAdd to make it faster?

Sorry for my bad english, and thank you for your replies :)

Replace your _ArrayPush loop with this:

For $i = 1 To UBound($retArray) - 1
  $korobIdArray[$i] = $retArray[$i][1]
