I just looked at it, and I can see why it was quicker.

In ANSI, to set a color, its "ESC[nnm" (where nn is a number). So minimum 5 chars before the character you want to draw, if you wanted to set the background color too, then it's another 3 chars ";nn" before the "m". So 8 chars to to set foreground and background color before the character.

In Avatar, its 3 chars "^V^An" a 62.5% saving, to set both the foreground and background.

So if you had a very ANSI centric display (which BBSs had), the saving over a slow medium noticably adds up... Back in those days, where disk space was a premium, the savings on disk would be noticable too.
