Sorry, but I have to disagree here, for me the performance
differences were indeed a dealbreaker for me to push lualatex as a
general purpose replacement in my department.
In documents of average complexity i normally get 30 page/second
performance. On more complex documents pdftex can be slower. I have a
2017 laptop so more modern hardware will gove lower numbers
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
Do you need otf fonts? Maybe t1 will do the job as well.
This performance difference is very noticeable. 8 s compile times are
fine, but having to wait 18 s interrupts my workflow.
In that case: run chapters when you work on them and not whole books ...
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.
mostly being 32 bit which is more memory demanding and memory access is
a bottleneck
