网络带宽压力测试教程视频_路由器压力测试-网络压力测试仪

网络带宽压力测试教程视频_路由器压力测试在我第一次知道有wrk这个工具的时候他确实还不太完善,要想测试一些复杂的请求还有点难度.现在wrk支持lua脚本.在这个脚本里你可以修改method,header,body,可以对response做一下自定义的分析.因为是lua脚本,其实这给了你无限的可能.但是这样一个强大的功能如果不谨慎使用,会降低测试端的性能,测试结果也受到影响.Req/Sec每个线程每秒钟的完成的请求数,同样有平均值,标准偏差,最大值,正负一个标准差占比….

1.需要安装一下编译工具，通过运行下面命令来安装工具：

# 安装 make 工具

sudo apt-get install make

# 安装 gcc编译环境

sudo apt-get install build-essential

2、安装完成之后安装git：

2.1.使用git -version命令查看环境是否安装git,如下图：

2.2.如果没安装就使用命令：apt-get install git (需要root权限就使用：sudo apt-get install git )

3、安装完成之后使用 git 下载 wrk 的源码到本地:

#下载命令

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

#切换路径到wrk目录下

cd wrk

#使用make命令编译环境

make

就 ok了.
make 成功以后在目录下有一个 wrk 文件. 就是它了. 你可以把这个文件复制到其他目录, 比如 bin 目录. 或者就这个目录下执行.

如果编译过程中出现:

src/wrk.h:11:25: fatal error: openssl/ssl.h: No such file or directory

#include <openssl/ssl.h>
