What is the best way to plot multiple graphs in parallel?

On page load, I need to plot 50-60 graphs, each with 3-4 traces and 80-90 points per trace. This process usually takes 6-8 seconds. Is there any way to accelerate this?
I tried scattergl, but it seems that it’s not for plotting too many graphs at the same time.
And the spec of machines that are used to render the page are quite good, so they can handle some heavy-lifting if necessary.

Using web workers might be worth a shot.

Even if it’s not blocking the main thread, it still takes that much time to finish rendering all graphs, right? I’m looking for a technique (with Plotly.js itself?) to reduce this rendering time.
