An example for the load of demeter is plotted her:
https://dev.gentoo.org/~dilfridge/load-demeter.pdf

Demeter is not only doing the binary packages, but also stages and isos for 
(natively) amd64, x86 and (via qemu) alpha, m68k, loong, riscv, aarch64_be.
Setting to keep it maximally busy are
MAKEOPTS="-j17 -l32"
EMERGE_DEFAULT_OPTS="--jobs 5 --load 32"

I checked the server auction a few days ago and didnt really see anything
obviously better than the AX102 (of course this may have changed in the
meantime).

A few remarks about the AX102 config:
* the main requirement for the machine is many cores and threads (now 8 cores, 
  AX102 16 cores)
* nvme storage: 2T (now) is OK, 3.8T (AX102) is better
  (mostly to have convenience buffer for bug fixing in qemu nspawns)
* no redundancy required, we can go a few days without package/stage updates,
  a reinstall is easy and the data is kept on other infra machines / 
  mastermirror too anyway
* AX102 is Zen4, which is nice since future-proof (x86-84-v4 anyone?), right 
  now we have Zen2
