High-Performance method to update data?

I would like to show some sensor data in (nearly) real-time. The new data is received using websockets. I use extendTraces to add new data. Unfortunately this is extremely slow (at the moment I update at just 100ms interval, but later the frequency will be increased) and browser will hang after a few seconds. Is there a high-performance way to update the data or is Plotly not designed for tasks like this?
Best regards
