implemented one of the remu3 from hacker's delight for practice, of course, rustc does this for us already (as do most other compilers). #rustlangpic.twitter.com/1TiOktb6fS

You're literally benchmarking an empty function. You're never using the result of your rem calls, so the compiler optimizes it away. You need to return the value or use `test::black_box`.
https://gist.github.com/sgrif/979b36a145c93a5c6cc67296dc4f0a49 … will actually benchmark the functions for an unknown value of `n` (and you'll see that the builtin mod3 is faster than remu3)

that's awesome. thanks. Still have a lot to learn. Here's a test run with your functions, also an attempt to introduce some randomness as well. Results still look the same - thoughts?pic.twitter.com/S17MlwdmPQ

Last time I tried, I needed to blackbox my output too
