significant delay when publishing with qos 1 or 2

saqirltu opened this issue 6 years ago · 1 comments

Hi,

I'm creating a MQTT client to publish and subscribe in Unity. I have the broker on a server on local network. When I use QOS 0 to publish, the latency is 1~5ms. But when I use QOS 1 or 2 to publish, the latency turns to 200ms. Both test results remain the same regardsless of different subscribing QOS.

Could there be any hint for this isssue? Many thanks!
