1) Yes and yes. (see https://sumo.dlr.de/docs/Simulation/Output.html#commandline_output_verbose). If you prefer, you can get the output in an xml file using option --statistic-output FILE (new in version 1.6)
2) We were mostly using meso for Berlin but the running time of 1 day is valid for microsim in a scenario without jamming (see https://sumo.dlr.de/docs/FAQ.html#how_fast_can_sumo_run). With jamming, vehicles spend much longer in the simulation and this slows it down. regards, Jakob Am Di., 5.
