Even if network datagrams moved at the speed of light and with no
serialisation/forwarding delay (which they don't), you're still going to
deal with several thousand KMs of distance; I'm positively surprised
you're getting such short round-trip times as it stands.
If you have any control over the application code, IMO your best shot is
to coalesce DB interactions into as few smarter DB queries as you can
for each higher order operation (eg: RESTful API calls), as you'll be
paying for that fixed RTT overhead for each command.
