Realistically, they should be able to do sub ms cache hits which land in the same datacenter. I know cloudflare doesn't have "named" datacenters like other providers but at the end of the day, there are servers somewhere and if your lambda runs twice in the same one there is no reason why a pull-through cache can't experience a standard intra data-center latency hit. I wonder if there is anything other than good engineering getting in the way of this and even sub us intra-process pull through caches for busy lambda functions. After all, if my lambda is getting called 1000X per second from the same point of presence, why wouldn't they keep the process in memory?
