@luke_nukem According to TechEmpower's Web Framework benchmarks, Rust is the lowest latency, but oddly enough performs around Node.js' level in throughput.
Used rust for 3 servers, one on my personal site for continuous integration, one for a standing desk, and now another for the backend of a business I thought up. https://rocket.rs was the best HTTP library out of the others I tried (Nickel, Iron). :D
