A very simple profiler to measure lengthy operations.
How to use:
Copy this file to your own tools folder and add the following line somewhere
near the start of your script.
local profiler = require(“profiler”)
To actually measure something, surround your code with the following calls.
profiler.run()
– lengthy code
profiler.stop()
The measured result will be shown in the terminal.

local PROFILER = {}

time_started = nil
time_stopped = nil
–[[profiling code]]------------------------------------------------------]]–
– runs the profiler, public
function PROFILER.run()
print(“Profiler running…”)
time_started = os.clock()
end
– stops the profiler and prints the time used, public
function PROFILER.stop()
time_stopped = os.clock()
print(“Profiler stopped…”)
print(“Time measured:”, time_stopped - time_started, “seconds.”)
end
----------------------------------------------------------------------------]]–
return PROFILER
