Salty and Sweet one-line Rust Runtime Optimization Library

SAS

SAS (Salty-And-Sweet) is an one-line Rust runtime optimization library.

Features

• NUMA-aware rayon: numa feature should be enabled
  • If you have 1 NUMA nodes, you can experience about 20% performance improvements if the tasks are completed at approximately equal times.
  • If you have 2+ NUMA nodes, you can experience extreme performance improvements.

Install

Simple one-shot mode

fn main() {
    // That's end!
    sas::init();

    // ... your heavy works
}

Advanced mode

TBD

Benchmarks

This sections describes the benchmark results. It uses default package features (zero-touch).

Note that the benchmark metrics are sensitive to process, so please benchmark each metric separately!

The lower elapsed time is the better.

Machine	OS (in Docker)	Kernel	Metric	Elapsed time (OFF)	Elapsed time (ON)	Performance Boost
