Okay, wow that is a LOT quicker. I haven't timed mine precisely buts
it's something like:

Compile 2 hrs, install 40 minutes (64bit), 120 minutes (32bit),
packaging probably like 5 minutes.

I have an NVME disk, but all my VMs (including this one) are on a SATA
disk, and it's a Samsung QVO 1TB one that was cheaper but also slower
(sustained write slows down to 80 MB/s eventually). Read is quick
though. IIRC it's presented as SATA to the VM too.

I'd better have a look at my configuration. Maybe do some disk and CPU
benchmarks. This is in virtualbox so perhaps it's yet another problem
with that, in the long list of problems I seem to have with virtualbox.
The VM has 16GB of RAM dedicated to it, how does that compare to your
system?
