Do BBR _only_ work with fq pacing or could fq_codel be used as a = replacement? Without pacing, it is not BBR as specified. Currently, only the fq = qdisc implements pacing. AFAIK, you need a working HPET for pacing to work correctly. A = low-precision timer would be a good explanation for low throughput under = pacing. - Jonathan Morton
