%%test.ctx.tex
\starttext
\dorecurse{100}{\externalfigure[t/PDF32000_2008.pdf][page=\recurselevel]}
\stoptext

$ time context test-ctx.tex &>/dev/null

real 0m1.829s
user 0m1.738s
sys 0m0.089s


$ time contextjit test-ctx.tex &>/dev/null

real 0m1.672s
user 0m1.591s
sys 0m0.079s


%% test-lualtx.tex
\documentclass{article}
\usepackage{pdfpages}

\begin{document}
\includepdf[pages={1-100}]{PDF32000_2008.pdf}
\end{document}

$ time pdflatex test-lualtx.tex  &> /dev/null

real 0m0.995s
user 0m0.967s
sys 0m0.028s


$ time lualatex test-lualtx.tex &>/dev/null

real 0m51.047s
user 0m50.256s
sys 0m0.689s

Note that all tests are done with  -O0  -g -ggdb3  without stripping the
binaries (i.e.: zero optimizations and size 2.5x bigger )
and that lualatex uses luahbtex, but I think that ratios should be the same.

(I need to check optex, btw)
