It basically comes down to how long you want to wait for results :).
The devguide lists [1] 2 cpu, 512 MB RAM and 30GB storage as the
preferred minimums, but that may or may not actually be enough
anymore, especially on RAM.

For reference, here are stats on my workers (formatting may be
destroyed by Gmail, sorry if so):
