Announcing rust-parallel: fast utility running for running commands in parallel

[aaronriekenberg]

Announcing rust-parallel, a fast command line utility to run commands in parallel and aggregate their output.

https://github.com/aaronriekenberg/rust-parallel
https://crates.io/crates/rust-parallel

Has a similar interface to GNU Parallel or xargs.

Started as an exercise to learn/practice tokio and async/await, but beginning to be a useful tool on its own.

Running parallel commands is a nice use case for tokio tasks that does not involve network I/O.

It is very fast in some small benchmarks. On my laptop it is:

• More than an order of magnitude faster than GNU Parallel (written in perl)
• 35-40% faster than xargs (written in C)

Interested in any feedback.

Thanks!
