@haoranyang2022 Hi, thanks a lot for your feedback, but EMQX and MQTTX are maintained by two different teams, so I moved this issue to MQTTX project.

The count printed by the bench tool isn't accurate, the server count is recommended.

@892744577 Sorry for late reply, please list your commands about publishing and subscribing and your hardware configuration to help us judge the problem.

`-c 30000` means 3w connections, and `conn` command only connect to MQTT broker without publish or subscribe.Your error is `connect error - timeout`, it means connecting to the server timeout.

@ig0r `einval` is a posix error, it usually occurs because the connection is broken, but the socket is still trying to send data. If you want to know the reason...

@fengjianjun1 Sorry for late reply, the bench tool doesn't support specifying payload yet.

@ryanwinchester Thank you for using emqtt. In general, if the connection fails for the first time, it means that the server has not been started or there are other problems,...

@mwallnoefer Sorry for later reply, could you join the project again via https://github.com/emqx/qmqtt/invitations, thanks for your efforts!

@berayb It seems that it has timed out waiting for the server to return a response.

@berayb Sorry for late reply. Can you provide a packet capture record?
