i think the techempowered benchmarks [https://www.techempower.com/benchmarks/ https://www.techempower.com/benchmarks/] don't show a pretty picture for swift-based web framework. But hopefully swift nio will change all that..

It literally only compares itself to slow, interpreted languages and other, even slower Swift frameworks, with the singular exception of Go, where they're using Gin, which is a rather slow Go framework. Gin is at literally 10% of the performance of the fastest Go framework, as shown here: https://www.techempower.com/benchmarks/#section=data-r16&hw=ph&test=plaintext https://www.techempower.com/benchmarks/#section=data-r16&hw=... So, when you cherry pick benchmarks, it can _look_ kind of fast... but then the unbiased TechEmpower benchmarks show Vapor operating at 20% of the speed of Gin. Which is 2% of the speed of the fastest Go or Rust web framework. "50x faster to pick a different language" != "even remotely great performance."

  I’m not sure this is a great benchmark (detailed in a comment above), but I think it’s undair to criticize a web framework for comparing itself to Django, node/express, Elixir/Phoenix. While dynamic languages, there’s billions of $ running on those frameworks and to present yourself as a fair alternative to those is good enough. (I have no personal interest in Swift on the server, I use Go/echo)

> We were pleasently surprised to see Vapor coming in first as being asynchronous does not really help with plaintext benchmarks. Plaintext benchmarks are really only good at testing how fast a web framework is capable of parsing and serializing HTTP headers. I did not look if other benchmarks were released but this is probably not the best representative.
