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_port5557)指定主机的IP及端口号。 # -*- coding:UTF-8 -*-ProjectName : pyExamples FileName : locust_demoDescription : Time : 2024/1/4 下午11:30Author : Qredsun
