Just pinning, the rest is stock virtio features like mergeable rx buffers, GRO, GSO (tx mitigation is actually disabled). Certainly doesn't show throughput in terms of cpu cycle cost (scaling) nor latency per-packet (exit and mitigation). thanks, -chris -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
