I understand that why it is slow, but the problem is that the difference is too 
high.
My book has lots of math, so perhaps that is the reason.
Option 1: Buy or borrow a faster computer. You'll get your desired speed-up far 
faster than waiting for Hans to make changes, even assuming there is something 
that can be changed. I'd recommend a Mac M3 :-)

As tex is a single core process (ok, the os might delegate some file handling 
to other cores) it benefits from  jump in core speed. I use a 2017 laptop with 
a reasonable fast intel xeon.  I have a few docks spread round with different 
resolution monitors (1920x1200, 2560×1440, 4096×2160) and performance also 
depends on the connected monitor.

I'd be curious to know how much these new processors impact performance over 
time because the ages of dohbling performance every year are past.

I mentioned the Mac M3 because it's not the cores that make the difference but 
the speed of the SSD. So reading the source and writing out the result, plus 
writing/reading any intermediate files is astonishingly fast on the Mac. Also 
the RAM is on the same die as the chip so RAM access speeds are high. Even if 
the app is single-threaded, the speed increases are significant - in fact 
especially when the app is single is threaded. :-)

File caching helps a lot indeed. Just compare

  context --make

after a reboot with the second or third time after that.
