Very helpful

Sometimes the difference between some codes performance can be very little, but... every little helps, specially if it comes to optimization.
This tool helps a lot when it comes to get these "little helps".

Great idea, but needs calibration or something

When I downloaded this program, I ran it without making any changes whatsoever. Out of the box, test 2 ran faster every time by 8% or so. Looking at the code, I am surprised to see that both test 1 and test 2 have nothing in them. Why then is test 1 slower than test 2? Beats me.

You will notice that when running identical code blocks that they will not have exactly identical performance scores. But read the documentation for an explanation of the accuracy of the test. It is explained in detail there, in the section, "Understanding the outcomes and limitations of the SPT test."
