You can get an awful lot of customers just by being in Ashburn VA with direct connects to to the big cloud providers. Most queries to a DB like mongo are slow enough that 1ms of network latency is just noise.
Strange. MongoDB has been consistently the fastest database I've ever used. Especially if your data model is document orientated.
(Apples to oranges, sure, but Postgres has the capability to be a great document store as well.)

You shouldn't be using MongoDB for anything but documents.
