一.安装测试工具

1.安装 ab 测试工具

1.安装

yum -y install httpd-tools

2.简单使用

ab -c 12 -n 500000 http://192.168.30.171/
    -n requests     Number of requests to perform
                    执行的总请求数
    -c concurrency  Number of multiple requests to make at a time
                    并发数

2.安装 awk

https://github.com/wg/wrk

1.安装

git clone https://github.com/wg/wrk.git
cd wrk
make

2.简单使用

./wrk -t12 -c400 -d30s --latency http://192.168.30.171/index.html

    [root@temp-02 wrk]# ./wrk 
    Usage: wrk <options> <url>

                                指定 Lua 脚本文件
        -H, --header      <H>  Add header to request
                                添加请求头
            --latency          Print latency statistics

二.测试结果展示

1.测试服务器配置

CPU     8核
内存    8G

[root@temp-01 logs]# cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)

[root@temp-01 logs]# /opt/tengine/sbin/nginx -v
Tengine version: Tengine/2.2.2 (nginx/1.8.1)

2.打开和关闭 Nginx 日志测试对比

1.关闭 Nginx access 日志

3.总结

关闭日志基本维持在32.7万/秒以上
打开日志基本维持在25万/秒左右，低了7万多

3.worker_processes 对性能的影响

跟【1.关闭 Nginx access 日志】测试配置除了将 worker_processes=auto 改为 worker_processes=1 外，其他全部一样

1.worker_processes=1

Transfer/sec:    260.83MB

4.总结

worker_processes=1，基本维持在不到6万
worker_processes=4，基本维持在17万
worker_processes=16，虽然线程调成了16，但是由于 CPU 还是8核心，所以性能并没有提升，还是维持在32万左右
worker_processes=16，并调整 CPU 为16核心，还是维持在32万左右
                    因为在每秒32万左右的情况下，请求 Nginx 默认主页的时候网络带宽占用已经达到1000M，所以此时的瓶颈已经不在 CPU
