This is a 720 page novel (first run with this LMTX version, some
fonts were still uncached):
mkiv lua stats > runtime: 19.275 seconds, 720 processed pages, 720
shipped pages, 37.355 pages/second
so what if you add to the top
\enableexperiments[fonts.compact]
ok, updated to latest LMTX, first run, all fonts still uncached:
mkiv lua stats > runtime: 19.025 seconds, 720 processed pages, 720
shipped pages, 37.846 pages/second
system | total runtime: 73.873 seconds of 73.964 seconds
real 1m13,971s
user 1m10,581s
sys 0m2,312s
next run, with fonts.compact:
mkiv lua stats > runtime: 19.327 seconds, 720 processed pages, 720
shipped pages, 37.254 pages/second
system | total runtime: 19.353 seconds of 19.453 seconds
real 0m19,461s
user 0m18,966s
sys 0m0,386s
without fonts.compact:
mkiv lua stats > runtime: 19.252 seconds, 720 processed pages, 720
shipped pages, 37.398 pages/second
system | total runtime: 19.283 seconds of 19.379 seconds
real 0m19,385s
user 0m18,943s
sys 0m0,380s
minimal difference.
the differences are mostly in loading times (say 10 times some cjk font
or math font)
the best way to check if compact mode was active is to check if the
number of font instances changed
for the record: compact mode actually has more overhead in the engine
but it is compensated by other aspects of it
