The following file (currently not "approved by the community”) compiles in 2.2
seconds with lualatex and in 0.3 seconds with pdflatex with a precompiled
format. That is over seven times slower. When I add four pages of meaningful
content (text and equations) the times are 2.5s and 0.5s, still five times
slower. This is meant to be an illustration only, but not so small to be
meaningless. The minimal file: \documentclass{minimal} \begin{document} Hello
World! \end{document} still takes 0.7s with lualatex.
