I agree with Alex here. Performance is the only reason I haven't switched to lualatex for all my documents yet. For instance, I get the numbers 8 s for pdflatex 12 s for lualatex with the same TFM fonts 18 s for lualatex using luaotfload and fontspec instead This was for a math heavy document of about 600 pages using large OTF fonts. This performance difference is very noticeable. 8 s compile times are fine, but having to wait 18 s interrupts my workflow. Note that I did not spend time to figure out what causes the slowdown. It might be harfbuzz, but it also might be fontspec, which wouldn't be luatex's fault. Achim
