[NTG-context] Re: Why LuaMetaTex is so slow?

Of course we'll never be as fast as (pure) plain tex (no layers added) or latex (which often is advocated as faster than context).

I was curious, so did a quick experiment: typeset \input knuth 500 times. Here are the results: pdflatex: 547 pages/sec lualatex: 308 pages/sec MKIV: 130 pages/sec LMTX: 147 pages/sec Interestingly, pdflatex, lualatex, and MkIV all generated pdf with 1112 pages, while LMTX generated a pdf with 1250 pages. Both MkIV and LMTX take the same time to run (8.5 sec) but LMTX generates more pages so it is faster. Of course, this is a meaningless experiment from a practical point of view as a 1000 page document will be more complex than just text. Aditya
