Realtime data cpu usage

Hello

My task is to show in one window four real-time graphs with six curves in each. The X axis shows the current time, the refresh rate is 3 Hz.
I use Plotly.extendTraces method to add new points to the graphs and Plotly.relayout to move along the X axis. In this case, CPU Usage is about 12%.
Could you help me reduce it. Maybe I do something wrong.

Hi @kvn
