Implementations that use advisory locks like https://github.com/que-rb/que https://github.com/que-rb/que are much more efficient (atleast when I last tested) and will easily reach 10k job/s on even very modest hardware. There is a Go port of Que but you can also easily port it to any language you like. I have a currently non-OSS implementation in Rust that I might OSS someday when I have time to clean it up.
