Matz も驚く Crystal
これ、Rubyでもそのまま動くんじゃないか？ Crystalすげーっ。 https://t.co/pO0F0vqTly

Language Goals Ruby-inspired syntax. Statically type-checked but without having to specify the type ...
http://crystal-lang.org/
ruby と殆ど同じシンタックスが通る様です。
# A very basic HTTP server
require "http/server"
server = HTTP::Server.new(8080) do |request|
HTTP::Response.ok "text/plain", "Hello world!"
end
puts "Listening on http://0.0.0.0:8080"
server.listen
しかも native code が吐けるらしい。ならばとベンチマークを取ってみた。CRuby 側は以下の sinatra。CRuby は 2.2.0p0 を使用。
require "sinatra"
set :environment, :production
get "/" do
content_type 'text/plain'
"Hello world!"
end
$ ab -k -c 10 -n 10000 http://localhost:8000

比べ物にならなかった。ただ、h2o や http-server だとファイルをサーブしたとしても 28000req/sec から 30000req/sec は出る環境なので、Crystal のネイティブコードがめちゃくちゃ速いという訳ではない。
