You've linked to ping/ICMP statistics, TCP is a more common use case and thus tends to be more representative of real-world applications. 100ms is a fairly realistic 90th percentile in my experience, 150ms could be in the 95th.

The extra time it takes to process a TCP request compared to ICMP traffic is the same regardless of whether or not you're using an edge computing platform. It seems to me that what actually matters is the difference in latency, not the absolute numbers.

That's why I think the article is incorrect when it claims that running an app in US East "adds an extra 100-150ms of latency". Not all of this is "extra". Only about 55ms are.
