I've got a t1.micro instance that can easily host 3 rF1 sessions but one rF2 server brings the server to its knees (25% CPU with no one racing and 100% with one client and 10 AI cars). I'm happy with AWS and so far the price has been quite reasonable (I'mon the 12-month free trial and pay a little extra for more storage, etc). I'm assuming what's hurting me here is the low CPU allocation for t1.micro. For anyone using AWS, what level of instance is needed to run rF2?
