They run over the network (no, I wasn't trying to cheat, but while stracing to debug my own code, I could see it sending for each query). Each track is split up into 1000 tests; you can run the separate tests concurrently; which more or less eliminates the latency as the largest test permits 'only' about 400k queries.
