Yeah those response times are in the realm of “why would I even consider that”. If I am trying to tune my db queries to have p95 latency of 1ms (for example) there’s no way I would choose an architecture that then threw that all out the window with ~100ms network latency. Hopefully I am misunderstanding those numbers somehow.

I saw this earlier and thoroughly didn't understand what is going on with that. I can't make any sense of why that would be so high.

Feels like a better test would be for the healthcheck to time the query RTT and report that back. Completely remove the web request from the equation.
