For what it is worth, I have a math book (lots of math and references
back and forth and some figures) and the 300 pages compiles in around
10s, so 30 pages/s. I don't have too much to compare with, and that is
a bit slower than your 40 pages/s (but 40*30 is 1200 and not 450), but
I consider that pretty fast.

One thing you can try is \enableexperiments[fonts.compact] (as it
sounds, it is still experimental).

Also, if you do not provide any example code, it will be difficult for
people to guess how _you_ can speed up your compilation (if at all).
