Benchmarking the cost of array bounds checks in Rust code: https://blog.readyset.io/bounds-checks/
The author even patches rustc to make sure *all* bounds checks are gone, in order to compare the performance!

Cute benchmarking technique for choosing sample programs in a benchmarking suite: perform principal component analysis to avoid redundancy!
I really like instruction counts for measuring performance. It's not perfect, but it's a very stable metric, even if I'm listening to music whilst developing and benchmarking.
I really value builds, lints and coverage metrics on pull requests. This still feels like an underexplored area though.
There's no Travis equivalent AFAIK for performance. I'd love to have automatic benchmarking on contributions.
