speed

[Spider001]

hey can someone tell me what's faster

$i = 1
While $i <= 1000
    $i += 1
WEnd

or

For $i = 1 To 1000 Step 1
      $j += 1
   Next

thank you

You should consider that the purpose is to do something in the loop, increment $j in this case

$j = 0
$hTimer = TimerInit()
$i = 1
While $i<=1000
   $i += 1
   $j += 1
Wend
$fDiff1 = TimerDiff($hTimer)

$j = 0
$hTimer = TimerInit()
For $i = 1 To 1000
      $j += 1
Next
$fDiff2 = TimerDiff($hTimer)

Msgbox(0,"", $fDiff1 & @crlf & $fDiff2)

just did something FOR is faster

Local $hTimer = TimerInit()
$i = 1
While $i <= 1000
   $i += 1
WEnd
ConsoleWrite(TimerDiff($hTimer) & @CRLF)
Local $hTimer = TimerInit()
Local $j
For $i = 1 To 1000 Step 1
   $j += 1
Next
ConsoleWrite(TimerDiff($hTimer) & @CRLF)

1.26831762137367
0.445866723284663

and this is a simple thing

your example give the same FOR is faster

1.45660970877584

0.433015928002023

While $i<=1000
   $i += 1
Wend

1.08589220138314

0.441117516332383

Yes

If $i is the local var only used to step inside the loop, your example should be

Local $hTimer = TimerInit()
$i = 1
While $i <= 1000
   $i += 1
WEnd
ConsoleWrite(TimerDiff($hTimer) & @CRLF)
Local $hTimer = TimerInit()
Local $j
For $i = 1 To 1000 Step 1
 ;  $j += 1
Next
ConsoleWrite(TimerDiff($hTimer) & @CRLF)

And the answer is even more obvious 

[Spider001]

I did a counter at the FOR because there is one to let the WHILE work.

So both has something to do the same fair play

may I suggest >this and >this.

that's a good one Detefon '?do=embed' frameborder='0' data-embedContent>> thanks for this one

Just as an FYI for the next time you, or anyone else, has such a simplistic question I'd like to suggest to you to try it before asking. It would have taken FAR less time to test the two methods with a timerinit/timerdiff, than it took to find the answer here.

That coding whas faster then finding the link else i maybe not code that or maybe i did even whit that link . why make so big problem of it.

[BrewManNH]

Why ask a question instead of running the code and timing it yourself? Did you really need to ask the question in the first place is all I'm getting at. It's not a big problem, it's just you asking a stupid question that really didn't need to be asked.
