Some of it might be the difference in table sizes for the plain TeX executable. But the factor of 25 seems to fit rather well also with the LaTeX format test. Any idea where the bulk of this would be from? What would somebody wanting to use LuaTeX in a production environment do (apart from getting his head examined, I mean)?
Luatex is slower than normal tex, and I expect the values for dumping latex are about right.Dumping any format is quite a bit slower, because the format is a) bigger, b) more complex, and c) compressed.
What is wrong with that tex.tex file is a mystery. I have not seen such slowness here and do not (yet) comprehend what is going on. Is there any particular part where it hesitates, or is it just overall much slower?
No, just going slowly overall the way it looks, so it can't be kpathsea, I guess. The file is just generated by weave tex.web and then compiled either with tex tex or with (after luatex -ini plain.tex "\dump") luatex "&plain" tex I should probably repeat the test with pdfTeX rather than TeX, but I have my doubts that it will account for _such_ a difference. In particular when it is running in DVI mode. I have not yet looked at the optimization options with which LuaTeX gets compiled. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
