Some fun math for you guys.

I had a single API endpoint performing ~178 Postgres SQL queries.

  Setup              Latency/query   Total time
  -------------------------------------------------
  Same geo area      35ms            6.2s
  Same local network 4ms             712ms
  Same server        ~0ms            170ms

This is with zero code changes, these time shavings are coming purely from network latency. A lot of devs lately are not even aware of latency costs coming from their service locations. It's crazy!
