With 14 nodes between client and server that's known that we have
problems. We perform too many roundtrips between client and server
compared with MySQL. Possible solutions are:
- modify API to have big calls (like attach database, start transaction,
prepare statement and return first row - all in one call)
- make client delay more packets (i.e. make it collect everything needed
for a single packet representing mentioned big call from a lot of small
calls)
