Each ligature substitution is another check that needs to be made while pre-processing the stream for display. In isolation, you could probably add that in without inducing a noticeable increase in the delay. Add up all the rest, though, especially hyphenation and tracking adjustments for justification, and a 505 would crawl.

The Epson controller in the 600 probably makes a big difference, but I think that's largely because its paralellism frees up cycles on the main cpu (which is running twice as fast as the one in the 505).
