A narrow follow-up to the previously covered HRT bandwidth account: per-CPU BPF-map counters reduced contention; multiple transfer paths were retained rather than replaced by a universal proxy; overlapping eBPF, service-log and NFS observations were deduplicated before switch-total reconciliation. The common accounting therefore did not require a single transfer mechanism. These are additional implementation details from Eric Goldlust's October 12 account, without a new incident or measured trading advantage. HRTBeat.
