CDP rountrip time on a local machine is 100µs (0.1ms), it's not slow haha

"Thousands of cdp calls" from the link.

Cdp does add a good chunk of latency. Depends on what your threshold is.

An image grab is around 60ms and a snapshot can range from 40ms -> 500ms

The latency is pure data movement. It's like the difference of using ram vs ssd vs data from the internet.

		yeah but good luck getting rid of that with a browser extension, you're just moving the latency around / moving it to chrome.runtime message passing.
