Timing your functions can be done by using os.clock(). Example: https://forum.renoise.com/t/renoise-tools-speed-optimization-initiative/45510

:blink:I read over the whole topic to tools speed optimization, but I did not remember that you just used that, thanks!I will definitely use this os.clock() to optimize my tools…

local x = os.clock()

function name_func()
  --content  
end

print(string.format("elapsed time: %.2f\n", os.clock() - x))

This is very interesting!!!
