Abstract: A weakly ordered doorbell at least reduces the cycle cost of talking to a device. This may manifest as simple performance improvement, but it also allows a reduction in the number of jobs batched into a single doorbell—current DPDK (Data Plane Development Kit) code (for example) batches larger numbers of packets behind a single doorbell to amortize the per-packet doorbell cost. Reducing the number of packets at least provide a better latency profile.
