PHP7+Swoole/Nginx/Golang性能对比

QPS对比

使用apache bench工具对Nginx静态页、Golang Http程序、PHP7+Swoole Http程序进行压力测试。在同一台机器上，进行并发100共100万次Http请求的基准测试中，QPS对比如下：

注：Nginx-1.9.9的测试中，已关闭access_log，启用open_file_cache缓存静态文件到内存

Golang

测试代码

package main
 
import (
    "log"
    "net/http"
    "runtime"
)
 
func main() {
    runtime.GOMAXPROCS(runtime.NumCPU() - 1)
 
    http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
        w.Header().Add("Last-Modified", "Thu, 18 Jun 2015 10:24:27 GMT")
        w.Header().Add("Accept-Ranges", "bytes")
        w.Header().Add("E-Tag", "55829c5b-17")
        w.Header().Add("Server", "golang-http-server")
        w.Write([]byte("
\nHello world!\n
\n"))
    })
 
    log.Printf("Go http Server listen on :8080")
    log.Fatal(http.ListenAndServe(":8080", nil))
}

PHP7+Swoole

PHP7已启用OpCache加速器。
