I am looking to purchase a VPS for Discourse and I have two options to choose from. A 2GB 2 core server with 25GB of storage and a 2GB 1 core server with 20GB of storage just a dollar more. Question is; would it be worth if I paid for for the extra core? This forum will be the only thing running - maybe a separate website down the road on Ubutunu server. Just gathering thoughts to make the right decision.
