What my question is about is precompiled formats: If I put everything in the preample and precompile it, pdflatex takes only 0.56s. /Here/ is the big difference. When I'm typing a typical technical note, I have over the years developed a workflow where I use latex + editor as a wysiwyg-setup. With two windows: one for the pdf and one for the source, recompile almost once for every sentence or equation. /It is here/ where the difference adds up. Judging by the other posts sparked by my question, I'm not the only one that feels the difference.</div><div><br></div><div>I readily admit that luatex is a wonderful piece of software and I really appreciate the work you have done.
