Description
The following script is used for testing the speed of LSL snippets. The script was written in LSLEditor. The script should work fine in both mono & LSO.

Directions
Go to an empty/script free private sim and detach any of your scripted attatchments. Create an object and place this script inside. Modify the "test()" and "clearvariables()" with whatever code it is that you want to test. Set the number of trials, the testcounter, and the test name. Save the script. Touch the object to begin the test. (If the script takes too long, reset).
The script provides min, max, avg, median, total time, and standard deviation.
You may need to run multiple trials as the script as all of SL is not always accurate/predictabl

//Name: Speed Tester.lsl
//Purpose: To test the speed of certain LSL snippets.
//Technical Overview: Uses 2 loops, one for trials, one for the test counter
//Directions: This is meant to be used by scripters, it should be easy to use. Modify the test() with your snippet, and touch to begin the test.
//Compatible: Mono & LSL compatible
//Other items required: None
//Notes: If it takes too long, simply reset.
// Do the test in an empty region, with as few script as possible to prevent contamination. (Make sure you aren't
// wearing scripted attatchments).
// This test is not 100% accurate, but it should give you a good idea as to whether or not something is faster.
// Anymore than 50 trials may not get printed out in the csv due to charactar limit.
