Hello Andreas, while looking through the osmo-pcu code to figure out why some connections stall we had some problems making sense of the elapsed time calculations in gprs_rlcmac_meas.cpp. Could you confirm/deny my assumptions about it or explain the idea behind it? I assume here you're calculating the duration of the measurement period so far and since you want to have sub-second accuracy you multiply everything with 128. Why 128? Is it becasue it simplifies the throughput calculation? (tbf->meas.dl_bw_octets/elapsed in gprs_rlcmac_dl_bw()) Is the intention here that the duration of the measurements is supposed to be one second? So every second these measurements are printed out and reset?
