google app engine - Does Firebase's lack of region support have a significant impact on app performance? -


firebase doesn't support regions. understanding is based in central google cloud region.

if serving app in london, in turn calls google cloud function, in turn calls google app engine, in turn calls database, i'm under impression involve circuitous routing.

for example:
1) web application served in london (cdn) ->
2) firebase database (us central) ->
3) google app engine (us central) ->
4) database request (london, uk) ->
5) written firebase database (us central) ->
6) served web application (london, uk).

with ~30,000km of cabling travel through, general impact on performance / lag sufficient affect app performance?

i recommend using firebase performance monitoring gain insights, run run load tests, or simulations make better call. https://firebase.google.com/docs/perf-mon/
