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++.
Rules for posting
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; //The larger the number here the better.
float current = time();
while (i < max) {
++i;
}
float t = (time()+-current)/max;
llOwnerSay("The function tool a total of " + (string)t + " milliseconds.");
}
}
Efficiency
++a and a += 1 are equal in speed (they compile to the same bytecode). a++ is slower.
