I think a lot of servers/database engines today tend to focus on horizontal scalability across large numbers of single-CPU instances and tend to ignore the efficiency benefits of a hybrid approach using fewer large instances.
Yes I imagine the thinking there is similar in your project, eg: Redis/CurioDB :: Node/SocketCluster (https://github.com/SocketCluster/socketcluster).
The performance table looks great, though what would be a recommended minimum underlying hardware requirement for production? (since the test is on a Mac-Air)
Hardware requirements would depend on your usage of course, it's like asking about the length of a piece of string. :-)
Honestly though, the code probably needs a lot more eyeballs on it before it's production ready, which is why I posted it here.
Ah yes that is true regarding the usage/req :), but I thought you might have tried it in production with some requirement.
