emqtt MAX concurrent client benchmarking problem about emqtt-bench HOT 3 OPEN

@mingdong. I have no idea about the problems of your benchmark setup from your report. We usually benchmark the broker on qingcloud.com when a new release is ready. A single 12Core, 32G CentOS node can handle about 1 million concurrent connections.

You could check the statistics of TCP Listeners:

./bin/emqttd_ctl listeners

from emqtt-bench.

@mingdong I'm also facing the same issue,can you please share any workaround for that situation if you find any, that will be great help. Thanks.

Same here.. I used this guide and did everything...
http://emqtt.io/docs/v2/tune.html

But very strangely the maximum no of connection in my dashboard reaches only upto 3500-3700 and after around 3300 connection number of connection grows very slower and does not exceeds above around 3700. I checked my machine's ram and cpu usage.. they are also very low, so it is not the insufficiency of resources (CPU/Ram) on the server...

Any idea what else needs to be done.. ?
