async-runtimes-benchmarks

Contains (rust) code from https://github.com/hez2010/async-runtimes-benchmarks-2024 👏

This repository contains a few programs written in various programming languages. Each program spawns N concurrent tasks. The number of tasks is controlled by the command line argument. Each tasks waits 10 seconds and finishes. The programs finish when all tasks exit.

The purpose of those programs is to measure the memory footprint of concurrent tasks in different language runtimes.
