Equal Signs - Test Speed (.= \ = \ := \ = %)

[V for Vendetta]

".=" is fast and faster than "=" (500 000 rows took 5 000 milliseconds):

Code: Select all

File = Text (Test).txt

gui, add, text, w300 r10 center 0x200 vTextBox, Please Wait!!!	;"0x200" center text vertically (but "`n" or "`r`n" will not represent new lines)
gui, show

StartTime = %A_TickCount%

loop, 500000
text .= a_index "`r`n"

guicontrol, , TextBox, Done

FileDelete, %File%		;Delete File

FileAppend, %text%, %File%, UTF-8	;"UTF-8" is the file Encoding \ UTF-16 \ UTF-8-RAW or UTF-16-RAW \ Empty or omitted: the system default ANSI code page, which is also the default setting.

gui, destroy

msgbox, % "Done - " A_TickCount - StartTime

guiclose:
exitapp

"=" is fast but slower than ".=" (500 000 rows took 10 000 milliseconds):

Code: Select all

File = Text (Test).txt

gui, add, text, w300 r10 center 0x200 vTextBox, Please Wait!!!	;"0x200" center text vertically (but "`n" or "`r`n" will not represent new lines)
gui, show

StartTime = %A_TickCount%

loop, 500000
text = %Text%%a_index%`r`n

guicontrol, , TextBox, Done

FileDelete, %File%		;Delete File

FileAppend, %text%, %File%, UTF-8	;"UTF-8" is the file Encoding \ UTF-16 \ UTF-8-RAW or UTF-16-RAW \ Empty or omitted: the system default ANSI code page, which is also the default setting.

gui, destroy

msgbox, % "Done - " A_TickCount - StartTime

guiclose:
exitapp

":=" is slow and the same as "= %" (20 000 rows took 11 000 milliseconds):

Code: Select all

File = Text (Test).txt

gui, add, text, w300 r10 center 0x200 vTextBox, Please Wait!!!	;"0x200" center text vertically (but "`n" or "`r`n" will not represent new lines)

I was actually wondering about this not too long ago, thanks for the info!!! Been planning a few speed tests myself on different things.
