This slow speed is one of the reasons the curses library and its descendants try to only repaint small sections of the screen using escape codes to move the cursor. Ironically it's also quite helpful with some modern terminals that are very heavyweight on graphical (pixel) redraws. E.g. I can refresh a TUI app using MacOS Terminal.app 30x a second using ncurses; but a naive wipe/redraw at that rate produces visible flickering and artifacts.

That's true, though it really surprised me how slow it felt. In the end I pumped the terminal speed up to 115k2 and it still felt very slow. Especially quickly paging through logfiles with 'less'. I remember spending part of my college days on green screen 9600 baud terminals (before they bought enough X terminals for everyone) and they felt snappy back in the day. And there was already a lot of TUI stuff going on back then. And in those days I didn't even know about gnu screen (or today's tmux) yet! I think I've just gotten spoilt with today's computer performance.
