There's some context missing here. AFAIK the author of the repositories was specifically doing micro-benchmarks here to inform the design of his https://github.com/cornelk/hashmap library. I think for that use case (designing a high-performance lock-free data structure), that kind of micro-benchmarking makes a lot of sense.

That hash map looks good and I'm thinking we'd probably benefit from using it on the hot path of some code we have that needs to be highly scalable.
