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

This is a complex topic, but to borrow from a recent post , web performance expands access to information and services by reducing latency and variance across interactions in a session, with a particular focus on the tail of the distribution (P75+). Consistent performance matters just as much as low average latency.

Chip design choices and silicon economics are the defining feature of the still-growing Performance Inequality Gap. Sadly, data on latency is harder to get, even from Google's perch, so progress there is somewhat more difficult to judge. Don't pay a lot for an Android-shaped muffler.

The benefits to apps that adopt WebView-based IABs are numerous: WebViews are system components designed for use within other apps. CCT's core design is sound and has enormous potential if made mandatory in place of WebView IABs by the Android and Play teams. There's reason to worry that this is unlikely.

Today we have a wealth of tools, both OSS and commercial, all designed for cloud-native environments. To improve availability, we designed systems where components could fail separately and avoid single points of failure. There is a downside to fetching this data on-demand: this adds latency to the first request to a cluster.
