“ …on mobile networks, [when] compared
to wifi networks, the routing overhead of
individual requests is much, much,
much larger. Setting up the connection
is a significant portion of the api call, so it's
better to combine. Pure rest apis with
many small resource calls are
typically sluggish in a mobile app
that runs over a 3G network. ”
