Pegasos/A1 machines do the same, as this topic speaks about. These babies is like an accelerated old amigas, with g4 1GHz cpu. On my peg MOS2 boot time is about 2 sec. Just like on my pc booting winuae.
Ok you can do a lot of things faster, mos2/os4 has some new apps, but compared to linux or windows, the avaliablity of softwares is converging to zero. That's the real problem not just the speed.
