It adds /key=value projections, heap tracking for allocated bytes (B/op) and objects (allocs/op) per op, and pprof profiling. In this post, I am benchmarking varint and Prometheus Remote Write 2.0 decoding across Go and Rust to showcase the benefits of benchstat-like flow in Rust. I’m also sharing some fun learnings on the way (e.g., yes Rust is faster).]]>
