Depends a lot on your host cpu, I would expect 2x to 10x the speed of that
build.

For memory: as much as works on your simh setup.
I would add 1G of swap.

If disk space includes sources and everything you will need ~15G
(plus swap). If you do not build with build.sh -VDEBUG=yes a bit
less space might be enough.
