Description

This article describes a simple function which calculates the execution time for your asp scripts.
It's very useful to find the time elapsed between two points in your asp scripts (for example in scripts with DB calls).

How to use

First, you must include the following JavaScript functions in your asp script:

function y2k(number)   
{
   return (number < 1000) ? number + 1900 : number;
}
function milliDif()   
{
   var d = new Date();
      return d.getTime()
}
                  
function elapsedpretty(parm1)
{
  var elapsedsecs = 0
  var elapsedmins = 0
  
  elapsedsecs=Math.floor(parm1/1000)
  parm1=parm1%1000
  
  elapsedmins=Math.floor(elapsedsecs/60)
  elapsedsecs=elapsedsecs%60
  
  elapsedpretty=elapsedmins + " minute"
  if(elapsedmins!=1)
       elapsedpretty=elapsedpretty+"s"
  
  elapsedpretty = elapsedpretty+" " + elapsedsecs+" second"
  if(elapsedsecs!=1)
       elapsedpretty=elapsedpretty+"s"
  
  elapsedpretty = elapsedpretty+ " "+parm1+" millisecond"
  if(parm1!=1)
       elapsedpretty=elapsedpretty+"s"
  
  return elapsedpretty;
}

After that, just start your timer with the following line:

'[start section to be evaluated]
timeThen = milliDif()	

Between the two calls must be your asp time evaluated code.

'here's some time consuming script code (like db calls for example)
for i=1 to 2000000
    i = i+1
next	

And finish the time counter with the following code:

'[end section to be evaluated]
timeNow = milliDif()
elapsed = timeNow - timeThen
msg = "Process time in ms: " & elapsed &  elapsedpretty(elapsed)
response.write msg
