Browser update request seems to be slow

Hey team,

I need to monitor 6 devices, Each with 17 sensors and init it from Jupyter.
So I created 6 groups, each with subplot the display 17 scatter graphs with max data of 100 points.

Currently I feed them with random data every second and refresh with an Interval component.

The problem is that on strong I7 computer the update request from the browser takes around 2 seconds.

I implemented the dash side using one callback with 6 output objects. If I reduce the the groups to one the request takes around 350ms.

The fetch time period does not change if I set the interval to 5 sec.

It seems far to slow. Any idea?

Dash version is 1.20.0
Plotly version is 4.14.3
