I've been building with exactly the configuration specified in the README.MacOSX file. I thought at one time I needed --disable-concept-checks, but it turns out I've been mistakenly leaving off the 's' at the end for some time (which I guess means the bogus flag was ignored). I just built clean without it - after rerunning ./configure - to verify. I'm building on Tiger, but before 4/29 I'd been building on 10.3 without seeing major issues. I do see the increase in processor use that you report - both on the Mac and on Windows, increasing as the document grows but only if I hammer away at the keyboard. Normal typing doesn't hit that hard on the processor and even hammering doesn't give me delays. I don't know why we're seeing a difference, but I have the same results on three machines (Powerbook, Mini, G5). I'm exposing my ignorance here, but I remember having to download a gettext library at some point, from somewhere. Can a difference like this (assuming yours is different than mine) have an effect?
