Measuring performance in a hardware-agnostic way (lemmy.blahaj.zone)

Is there a way to measure performance without depending on the hardware, i.e. two entirely different computers get the same score for the same code?

I could probably run the program on a server or something, but something local feels more reliable.

Sure, but that makes a lot of optimizations nonexistent (e.g. cloning the input on an O(n) algorithm is "free")

You don't need to use big-O. You can calculate the full complexity in algebraic notation. It's just a lot more work as you don't get to discard terms.
