Impressive benchmarks. Reaching 1M msgs/sec on a 2 vCPU instance is a great showcase for Crystal. As a Crystal core member, I've always seen LavinMQ as a prime example of performance-oriented engineering, especially with how it handles I/O and minimizes syscalls to get the most out of the hardware.
If you want to see Crystal's concurrency and type system in a serious production environment, this is the project to check out. Kudos to the LavinMQ team for their work since 2020.
