+In this case information about performance is situated in "measDataCollection" section, consisting of latency and throughput parameters of performance, identifier of event producer and trafficModel with user equipment information.
+As PM Mapper is not maintaining the exact time of each event, that times are calculated in following way: (lastEpochMicrosec - startEpochMicrosec)/ number of events.
