New Alix board for 2013
-
Nesense, thanks for your efforts!
A good test scenario would be something like this I think:[Laptop (192.168.10.10)] - [LAN Interface (192.168.10.1) - ALIX - WAN Interface (1.1.1.1)] - [iperf server (1.1.1.2)] -

Sadly I can't do such a test right now since my WAN interface is running on 100MBIT and my other computer has its monitor at repair, i'll try to borrow a second laptop or something to do throughput tests ASAP.
BTW the thermal sensors aren't working.
Any idea how I can get the WLE200NX wifi card to work on pfsense? it uses the AR9280 Atheros chipset, there's this thread http://forum.pfsense.org/index.php?topic=55403.0 that mentions FreeBSD 9.x drivers working with it and that they're already on pfsense 2.1 but i'm still having issues.

here's a picture of the board:

Do you have some way to measure power consumption of the board?
For comparison, I measured the 2D13 at 3W AC idle through a reasonably efficient 12V power supply. Although IIRC it didn't change under load either, my meter doesn't have decimal resolution.

Document says 6 to 12W depending on CPU load. This is using the T40N CPU with a 9W TDP. plan is to change to T40E with a 6W TDP.
-
The documentation claims about 5W DC for the existing Geode platform though, and I measured lower than that AC, so I was wondering if measured power could again be lower.
-
Some of those plug-in power meters claim an amazing accuracy. However if you look at the cost if genuinely accurate power meters it's hard to believe. That's especially true for switching power supplies. It wouldn't surprise me to find they misread by a few Watts at very low power levels.

BTW it also states that PoE is not supported and never will for the APU board.

I've found mine to be reasonably accurate (it's not a cheap one), allowing for rounding without any decimals of course, and it does account for PF for instance. But I will try to get around to measuring DC draw.
It's not like consumer meters are £1000 worth of kit either.
-
Well exactly. My meter was ~£30 and seems to work OK. It measures Watts and VA so I guess it allows for powerfactor but it's clearly not true RMS so I doubt it reads 'spiky' waveforms too well. I still use it though because it gives me a good idea of what's drawing power and if I reduce that. Just keep in mind that real power meters that have 0.01% accuracy are, as you say, many thousands of £/$.
Anyway 6W is low enough for me. :)

OK here are some DC measurements from my 2D13 for comparison.
Voltage set at 12.0V
Idle: 0.28A 3.36W
~60Mb/s download (speedtest): 0.34A 4.08W
Max CPU, achieved withdd if=/dev/urandom of=/dev/nullor burnMMX: fluctuating between 0.37 and 0.39A 4.44-4.68W
-
Nice. :)
I'm certainly prepared to believe those measurements, assuming the psu holds 12V well enough. ;)How many Watts do you think are lost in the PSU, it's efficiency?
Given the small variation in power, 5W max, perhaps the supplied psu is still highly efficient at 3.36W.
Pure speculation time: I would expect to see perhaps 0.25-0.5W loss in the PSU in which case I would hope an AC side power meter should read 4W (if it doesn't display fractions of a Watt).User phil.davis could tell us a lot about the power consumption of the old Alix board since a lot of his sites are solar powered.

Yeah I was using a bench power supply and double-checked voltage and current with a couple of multimeters.
The PSU I normally use, and did the AC measurements with, is a 60W FSP one which I also use to supply some other network kit (I've also measured with some 12W PSUs with the same results IIRC). It's efficiency level V so >87% average efficiency, although the points for that average are measured at 25, 50, 75 and 100 percent load, so it may not be that efficient at <10% load.
Either way, you're likely correct the AC meter should be displaying 4W. The resolution isn't ideal for measuring this low TBF, but it's ballpark accurate at least. Even being less than half a Watt out and clipping the decimals rather than rounding up could explain why it displays 3.

I ran iperf again, this time using two computers connected to the board on individual port, all running 1000baseT, iperf server on a windows 8.1 box, and client on macbook laptop running os x 10.7.5, only running squid on pfsense 2.1, here are the results:

Nice! :)
If you run 'top -SH' on the apu board what does the cpu usage look like during that test?Not sure how netio is measuring that udp speed but most of those numbers are far higher than you could get down a gigabit connection so it looks like it's buffering somewhere.
Steve

It's the UDP transmit speed, but of course most of that won't make it on to the wire, so it's essentially irrelevant. The receive speeds are what you'd want to look at, but it seems something is up with the testing as they're zero, or close to it, on most of the runs.
Edit: I've just tried the UDP benchmark myself and it never reported above roughly 113MB/s, so it seems it works a bit differently than I thought, and something's up with the above benchmark.
-
FYI I've just finished doing iperf testing on an older alix 2d2.
Sadly I did not take power usage measurements while testing.Full results at: http://forum.pfsense.org/index.php/topic,70911.0.html
Short version, okay for up to 50 Mbit, can do up to 95 Mbit but you're wringing the nuts off there.
-
How are you testing that? A throughput test is what's needed, iperf running on two separate machine not on the pfSense box.
326Mbps seems disappointingly slow. :-\Steve
We ran a throughput test on a very similar box (same cpu, same NICs), and were disappointed.
Our APU only recently arrived.

i heard this new alix apu gets pretty hot, almost 81.5 degrees
