Perfect, problem solved! Infact, those queries seem to take 0 seconds now (I guess not waiting for any TCP ack or something). At first I thought you meant it was to be enabled on the SUMO side in configure, but then I realised you meant change the socket option on Java (at least, that's what I've done!).
Anyway, thanks, I'd not have guessed that was in the problem for ages!
