It's so strange that we talk about languages being slow, and have done for years. Computer performance has increased so much in this time.
https://hbfs.wordpress.com/2009/11/10/is-python-slow/ (shared on HN in 2009) discusses Python being slow. My underpowered Thinkpad has 20x the single-threaded performance! https://www.cpubenchmark.net/compare/73vs3766/AMD-Athlon-64-4000+-vs-AMD-Ryzen-5-PRO-4650U
Maybe *relative* performance of languages matters more?
I have mixed feelings about the equality trait in Rust.
I have types where sometimes I want to compare by structure, and sometimes compare by reference.
I can only implement Eq for one, so which do I pick?
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!
