Rust optimizations benchmark

This project is a benchmark comparison between different Cargo compiler options (LTO, codegen-units, etc.)

Profiles available

There are three main profile available (plus the standard release):

release-light
release-medium
release-extreme

Original benchmark source-codes

This repository is based on the work of kostya, original repo could be found here.

Sample benchmark

Here a list of executed single-threads local benchmark split by optimization level.
