Refresh rate instruction not respected


I have installed Grafana in local on my mac and I’m trying to configure him in order to have a refresh rate of 1s or 100ms. I’m using Infinity plugin in order to get json data (with HTTP protocol) from my ESP32, but when I set the refresh rate to 1s or 100ms, Grafana achieves to send a request to my ESP32 every 5-10 sec (very slow :/). I’ve already tested the speed of my ESP32 and it doesn’t seem to be the problem.

So if anyone has any idea of how to solve my problem, I would thank you very much !
