If restricting everyone to the same system, then can force every contestant to use https://tio.run and the on-site bench-marking found below "debug" -> "real time" as efficiency metric. [Example](https://tio.run/##S9ZNT07@r5yZl5xTmpKqYFNckpKZr5dh9z8zr0QhNzEzT0GjLD8zRZOrmktBoaC0pFhDKSM1JydfoTy/KCdFUUnTmqv2//9/yWk5ienF/3X9jQE). 

Advantages:

- No matter how (in)accurate, this gives everyone the same conditions and the same bench-marking system. It is fair.
- Multiple programming languages and compilers are possible. Competitions between solutions in the same language and/or other languages is possible.
- We already use TIO for most challenges.

Disadvantages:
- Heavily biased towards a specific target - I think it runs on x86_64 Linux?
- Execution times are rather arbitrary with poor accuracy. This is a poor benchmarking tool by professional standards, but maybe for this purpose we don't really care?
