The difference in weight between the two architectures is interesting, but what we should focus on is the per interaction loop. The chief effect of the architectural difference is to shift the distribution of latency within the loop.

One distinct trend is a belief that a JavaScript framework and Single-Page Architecture (SPA) is a must for PWA development. It simulates a link with a 400ms RTT and 400-600Kbps of throughput (plus latency variability and simulated packet loss). Our baseline, then, should probably trade lower throughput/higher-latency for packet loss.
