Go beats Rust in speed and even C++ sometimes in this interesting performance matchup

• countwords

  43 209 5.9 Rust

  Discontinued Playing with counting word frequencies (and performance) in various languages.

There is a parallel.go in the repo, but it's much more complicated (5x as long) and doesn't perform as well as the optimized single-threaded version. https://github.com/benhoyt/countwords/blob/master/parallel.go

• llfio

  25 764 6.3 C++

  P1031 low level file i/o and filesystem library for the C++ standard

The problem of reading from stdin itself is a fraught venture, as you discovered with ios::sync_with_stdio, and this goes much further. If trying to think about performance, you would typically end up using solutions like LLFIO instead of working within the current standard library and there are similar performance-oriented I/O libraries for many languages.
