介绍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：

软件 QPS 软件版本 Nginx 164489.92 nginx/1.4.6 (Ubuntu) Golang 166838.68 go version go1.5.2 linux/AMD64 PHP7+Swoole 287104.12 swoole-1.7.22-alpha Nginx-1.9.9 245058.70 nginx/1.9.9

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

测试环境

CPU：Intel® Core™ i5-4590 CPU @ 3.30GHz × 4 内存：16G 磁盘：128G SSD 操作系统：Ubuntu14.04 (Linux 3.16.0-55-generic)

压测工具

ab -c 100 -n 1000000 -k http://127.0.0.1:8080/

VHOST配置

server { listen 80 default_server; root /data/webroot; index index.html; }

测试页面

<h1>Hello World!</h1>

进程数量

Nginx开启了4个Worker进程

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(“<h1>nHello world!n</h1>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。
