It is probably some local snafu on your system, because > lisp/Makefile.in I have here says Ugh, you are right - it was in the first patch, though I do not recall adding it. I made a fresh clone of the emacs repo and applied all the changes before committing. I'm attaching the combined patch which does not contain that non-sequitur. The profiles of the bootstrap dump and the dump with the loadup libraries byte-compiled is in read0 for 0.2 and 0.1 seconds respectively (barely enough to measure). When I summarize profiles of all the ELC jobs, though, the total time is about 5 seconds. It should be at least enough for a meaningful comparison, even though it is a tiny part of the overall computation time. If you're interested in measuring just read0, anyway. and not the cost of the entire activation of the various entry points to read0. Lynn
