I've used an 8 bit computer with a 300 baud modem. One bbs I dialed into was a 8 bit computer with a whopping 4mb of ram. It was the fastest response time of any computer I've every used. Everything was in ram, and coded in assembly with speed and low code space as the concern.

Modern computers should be much faster, but they aren't. They do more, but when you do something you notice the slow speed.
