Vim can lend you a few million cycles, if you need'em. Vim starts close enough to instantly that I can't tell the difference. Modern Vim on a real Amiga is probably pretty slow though.
I think Bram stopped trying to maintain Amiga support after 6.x. But I don't have an Amiga anymore and haven't paid attention in a long time. I was surprised when it was still supported a few years ago.
