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.
