My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

Each HTTP request that is required for the page needs to travel over the network and in turn this consumes energy on both the server and client. Without effective caching on the client, the server will see an increase in workload, more CPU usage and ultimately increased latency for the end user. Unfortunately, that’s not where it ends.
