I am trying a build a realtime monitoring system for high frequency data. To increase the performance, I used the extendData property of dcc.Graph() and websocket. So that, the brouser does not need to send request to get data.
I found that it still not increasing the performance as expected. The reason I found is, from the browser, I see (by inspecting network from browser) after some miliseconds browser is still sendng request and the initiator is the dash_renderer.
Mq question is:
- What dash_renderer do?
- why it is sending http request?
- and how to stop that?
