Also for me one of the biggest bottlenecks in HTTP seems to be the esp32 parsing the request header. socket.readline() seems to be very slow.

You could use HTTP directly with the espidf module. It’s more efficient because everything is implemented in C (with a Micropython API).
While only HTTP client is currently supported, I believe it should be pretty easy to add HTTP server.
HTTP/2 is also supported (but not documented yet).

Live video definitely needs some further thinking …

Another option is to avoid communicating with the web client directly.
Instead, the device could interact with some service on a remote server with TCP socket (or UDP or any other way), and the service would push the data to the web client.
