LoadRunner虽然不是开源工具，但安装Apache服务器后，我们可以使用其内置的开源压力测试工具ab进行性能测试。以下是使用ab进行测试的简单示例和结果分析：

ab -n 10 -c 10 http://www.google.com/
该命令会发送10个请求，并且每次发送10个请求。

100% 3184 (longest request)

注解:

- Apache的bin目录下运行。

格式: ab [options] [http://]hostname[:port]/path

-n requests: 测试的请求数量，默认为1

-c concurrency: 并发请求数量，默认为1

-t timelimit: 最大等待时间，默认为无限制

-w: 以HTML表格形式输出结果

其他选项可参考官方文档。
