How many machines are used for the test? Please be aware of that one network interface of a machine can only support maximum of 65k connections. So you should prepare at least several machines for your testing. Also, you can refer to [here - Chinese] (https://www.jianshu.com/p/3799302b2b3e) for JMeter optimization.

thanks, i've tried it, and i tried the emqx settings, found that it's not the problem is not from linux settings. it's my java broker project, use LinkedBlockingQueue to cache the netty event, and it cannot deal with so many event in limit time, and jmeter throw the time limit exceed exception. jmeter is fine.
