Big Sky :: Crystal と CRuby でHTTPサーバのベンチマーク
こちらの記事を見て気になったのでGoと比較してみた。
※ Goのプロセス数が1の場合の他に、全コア分使うコードでの測定も追記した。
Crystal
バージョン
$ crystal --version 15:13:21
Crystal 0.7.3 [bf72b07] (Sun Jun 7 16:17:59 UTC 2015)
コード
上記の記事とまったく同じ。
--release付きでビルドした。
Go(1プロセス版）
バージョン
$ go version
go version go1.4.2 darwin/amd64
コード
package main
import (
"fmt"
"net/http"
)
func handler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello World!")
}
func main() {
http.HandleFunc("/", handler)
http.ListenAndServe(":8080", nil)
}
ビルドと実行
$ go build main.go
$ ./main
Go(全コア使う版）
コード以外は上記1プロセス版と同じ。
コード
package main
import (
"fmt"
"net/http"
"runtime"
)
func handler(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello World!")
}
func main() {
runtime.GOMAXPROCS(runtime.NumCPU())
http.HandleFunc("/", handler)
http.ListenAndServe(":8080", nil)
}

Crystal速い。でもどっちも十分な速さではある。
Crystalの並行・並列処理の辺りがどうなっているかわかっていないので、
その辺りを追いかけてみたい。
追記
Crystalの作者であるasteriteさんから、spawnという並列処理用のコマンドがあると
教えていただいたので、試してみました。
100.times do
spawn do
sleep 1
puts Time.now
end
end
sleep 5
これで並列処理されなければ100秒以上かかる処理のはずですが、
実行するとすぐ終わります。
まさにgoroutineのような感じで素晴らしい。
まだ開発中のようですが、今後がとても楽しみです。
