More recent design practice has decided that it's cruising speed is a little to high, so one would expect the A340 to be slower. As a data point, looking at the BA timetable for JFK-LHR, the times vary vary from 6:40 (747-Classic) to 7:10 (767), and a direct comparison of the same flight number which switches between 767 and DC-10 mid season shows (for JFK-LGW), 7:00 DC-10 and 7:15 for the 767. So within the Boeing family, planes have got slower with the newer designs. On a personal note, I can remember flying LHR-LAX in the 70's in a DC-10, and watching in the next flight level a Lufthansa 747 ever so slowly overtaking us.
