I have, finally. It's been running for a week or so, now. OpenWRT was an _adventure_. The board is UEFI, not standard bios. And while it will merrily boot OpenWRT's non-uefi images off of USB, it won't boot the non-UEFI setup from the internal storage (I'm using the eMMC). So _that_ was fun (and I made some dumb mistakes that were especially fun to correct. But it's running OpenWRT 19.07 (and a UEFI bootloader before grub that's from ToT OpenWRT). Anyway, I have cake running, 950Mbps ingress and 35Mbps egress (modem is provisioned at 1.3G ingress, and a bit over 35Mbps egress). fq_codel was defaulted, in multi-queue mode. While I'm using cake on ingress, my local link hasn't been hitting the limiter very often: Tin 0 thresh 950Mbit target 1.5ms interval 30.0ms pk_delay 22us av_delay 9us sp_delay 2us backlog 0b pkts 243608193 bytes 250748364896 way_inds 13167720 way_miss 1245030 way_cols 0 drops 1075 marks 101 ack_drop 0 sp_flows 0 bk_flows 1 un_flows 0 max_len 69876 quantum 1514 Given that most of the hosts that I interact with are only about 10-15ms away, I'm probably going to change the interval target to better match that. Interestingly, while it has a pair of multiqueue NICs (i211s), the igbe driver isn't configuring them for RSS. Both output queues are being used, but not the ingress queues: wan interface: tx_queue_0_packets: 56635989 tx_queue_1_packets: 39777210 rx_queue_0_packets: 243646072 rx_queue_1_packets: 0 lan interface: tx_queue_0_packets: 85047897 tx_queue_1_packets: 162004500 rx_queue_0_packets: 111174855 rx_queue_1_packets: 0 Since I have housemates that don't appreciate me messing with the network during their meetings, I haven't gotten around to poking more deeply at that (or at experimenting with running cake on two ingress queues). That being said, I bench-tested this before I put it into operation and was able to see 940Mbps of iperf goodput through cake and NAT... Took all of a core, though (and that core was still cold and therefore potentially able to boost to 2.5GHz). I haven't determined how long it will take to thermally throttle, and if bandwidth suffers as a result. Pretty happy with it so far, though.
