Any stats on how much power it pulled during your tests and when idle?

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.
