Setting the RAM disk so high will mean you don't have enough memory for
the compilation, which will start swapping and everything will grind to a
near halt.

Lookup package.env on the wiki. I use rust-bin now, so this isn't an
issue for me, but my laptop has only 8GB and this is how I have it set
for chromium:
% cat /etc/portage/env/disk-tmpdir.conf
PORTAGE_TMPDIR="/mnt/scratch"
% cat /etc/portage/package.env/chromium
www-client/chromium disk-tmpdir.conf
I do similar for libreoffice and a couple of other heavyweights.
Another option, to be used instead of or as well as this would be distcc.
Once again, you can use package.env to apply this to selected packages:
% cat /etc/portage/env/distcc.conf
FEATURES="distcc buildpkg distlocks"
MAKEOPTS="-j36 -l4"
CFLAGS="-march=broadwell -O2 -pipe"
CXXFLAGS="${CFLAGS}"
