Adding one brower source multiplies the CPU usage

We use Zoom Rooms to get a sort of "connection" between the coffee areas within the company. Great idea, really. :)

Just for fun, I'm trying to overlay a browser source on that webcam. I've made a sound meter using a NodeMCU and a breakout board, and there's a simple web server on the NodeMCU witch updates as fast as it can (only the text):

Using OBS Studio with one camera maximised and the OBS Virtual Camera to Zoom Rooms results in a 4-5% CPU usage for OBS Studio, and everything is fine. However, if I add that simple web page it uses 35-40%, which results in the computer sounding like a jet engine.

What can I do to reduce the CPU usage for a simple browser overlay?
 
Hi, and thank you for replying.

Yes, I tried to reduce it to 10, 5 and even 2, but the CPU usage is almost not changed.
