it's hard to tell what exact consumpiton is becaue for instance when lua 
creates tables, they grow by factors two when then have to (maybe 5.5 is 
a bit less consuming)

on the one hand luametatex is more efficient than luatex due to all kind 
of ímprovements' but some nodes are larger so that takes more memory, 
which is only noticed when one has lots of text on a page (or keeps 
boxes stuff around)

anyway, not that much changed since the previous upload, so maybe you 
just stay below a threshold

I recently generated a 180MB document with 2500 fonts + metapost 
outlines of them and that could bump mem usage (with empty cache) to 30 
GB (less after fonts were cached) but normally we stay around 125 MB for 
a document. Anyway, tex mem consumption can often be neglected compared 
to other applications.
