Lots of people disagree with me that a += 1 is faster than +=a, but check out the [[LSL Script Efficiency]]... If you don't like it, change it and sue me :P.

This code will test the efficiency of what ever is in the while loop.

I've used i += 1 because I found it to be faster on the LSL Script Efficiency page.

Lots of people disagree with me that a += 1 is faster than +=a... If you don't like it, change it and then sue me :P.

//IMPORTANT: Only perform tests in an empty region to reduce contamination and be sure to wearing no attachments.

integer time() {
    string stamp = llGetTimestamp();
    return (integer) llGetSubString(stamp, 11, 12) * 3600000 + 
           (integer) llGetSubString(stamp, 14, 15) * 60000 + 
           llRound((float)llGetSubString(stamp, 17, -2) * 1000000.0)/1000;
//llInsertString(llDeleteSubString(stamp, 19, 19) + "000000", 23, ".")
}

default {
  state_entry() {
    //test variables
    float counter;

    //framework variables
    float i = 0;
    float j = 0;
    float max = 10000;
    float start = time();
    do {
      //test
      counter += 1;
      
    }while (++i < max);
    float delta = time();
    do ; while (++j < max);
    float end = time();//remove the time required by the framework
    float t = ((delta - start) - (end - delta))/max;
    llOwnerSay("The function in the loop took a total of " + (string)t + " milliseconds.");
  }
}
