Yes, with 2021.05.19 18:22, the file compiles again in lmtx! I'm also
trying your suggestions for improving the Lua code and rethinking my
tables for analyzing the vocabulary. Thank you for the quick fix! And I
hope there won't be any problem for other users - I'm aware that memory

on computers can differ vastly. I sometimes run ConTeXt on my raspberry
pi 3, which has just 1 G of RAM, whereas my newish iMac at home has 40
G. So it's difficult to find the sweet spot that will satisfy everybody...
Unless you use many huge fonts, running your document on a rpi 4 with
4-8 gb should work ok (we have a rpi 4 in mojcas compile farm connected
to an usb3 ssd). My laptop is from 2013 (decent intel 3840QM cpu + 16 GB
mem and ssd and so) and is about 3 times slower than the rpi 4 in the
luametatex manual.
Your file in mkiv does a decent ppm (is that an arm or intel mac?)
mkiv lua stats > lua properties: engine: lua 5.3, used memory: 601 MB,
ctx: 579 MB, max: unknown MB, hash chars: min(64,40), symbol mask: utf (τεχ)
mkiv lua stats > runtime: 22.310 seconds, 1068 processed pages, 1068
shipped pages, 47.871 pages/second
so I suppose in lmtx it's a bit faster and using less mem. Still less
mem than the GB's that e.g. firefox consumes after a few hours sitting
idle.
Concerning the sweetspot: I supose that on a laptop or desktop users are
okay, but in a vm (or instance) it might matter because there processes
have to fight over memory and cache (some is gained back by often faster
disk io because that gets delegated to another process). I try to keep
that in mind with luametatex/lmtx, which is why I spent quite some time
on a lower mem footprint. I have no clue what a modern cpu does compared
to mine (tex is single core).
(btw, the latest version should also be a bit more efficient / faster
with some huge cjk fonts that for some reasons have so many zero entries
that the tma file was 3 times larger than needed, but I suppose fonts
will always be a bit of an issue ... they have always been since tex
showed up.)
