LSL Script Efficiency

What is Efficiency

PAGE UNDER CONSTRUCTION!

Efficiency is how long it takes to run a script.

There are many ways to speed up scripts, such as using ++a instead of a++.

The following code snipit will allow testing of a function.

integer time() {
    string stamp = llGetTimestamp();
    return (integer) llGetSubString(stamp, 11, 12) * 3600000 + (integer) llGetSubString(stamp, 14, 15) * 60000 + llRound((float) llGetSubString(stamp, 17, -2) * 1000.0);
}


default {
  state_entry() {
    float i = 0;
    float max = 1000;
    float current = time();
    while (i < max) {
      ++a;
    }
    llOwnerSay("The function tool a total of " + (string)((time()-current)/max)) + " milliseconds.");
  }
}

Efficiency

++a and a += 1 are equal in speed (they compile to the same bytecode). a++ is slower.
