Personally, I find this a far less impressive demo of the SuperH SH-4 CPU than, say, Doom running on a graphical calculator. A http server (not https) simply opens sockets, writes a string, and closes the socket, a task which is usually purely I/O bound. Implement something basic like HTTPS (introduced in 1994) and watch this CPU grind to a halt.

I agree with the feeling, it's not really that impressive, but the HTTPS mention isn't accurate. Performance would be certainly lower, but remember the SH-4 was in the Dreamcast.

You can buy some niche boards[0] with SH-4, and I assure you, they can run Debian and they do SSL just fine.
