文化类网站建设方向阿里云上如何用iis做网站

背景：

使用默认的locust启动命令进行压测时，尽管已经将用户数设置大比较大（400），但是压测的时候RPS一直在100左右。需要增加压测的压力。

问题原因：

如果你是通过命令行启动的或者参考之前文章的启动方式：

• 命令行：

• locust 库方法：
  `

因为create_local_runner会创建一个LocalRunner，这个runner只有一个WorkerNode

解决方式：

• 单机：充分利用CPU每一个核心

  • os_start(True)，指定参数True``则充分利用cpu的性能，否则就和之前调用create_local_runner一样。 使用os、multiprocessing完成， 模拟的是命令行启动locust的操作.。
  • local_start(True),使用locust的库方法，根据CPU的核心数、线程数创建WorkerNode

• 多机：利用多台机器的能力提高测试压力

  • slave_start(master_ip, master_port=5557)，指定主机的IP及端口号。
