PC Engines apu2 experiences

I know what you mean mine does that aswell, i'm not sure if you can change it. If you have powerd enabled you can get a realtime frequency read out using the shell command powerd -v.

I don't think the dashboard freqency readout is just amd related, it behaves the same on intel systems too.

Thanks for that, good to know.

What transfer speed does the apu2 get from squid's local cache?

What transfer speed does the apu2 get from squid's local cache?

This is mostly also owed to the circumstance what storage drive is used in that case!!

I'd like to add what I've found and compare the APU1D with the APU2C4. Each test was run 5 times and the average is shown:

Some things stand out fairly obvious but I'll need some help determining what is going on.
First, it's obvious that enabling aes-ni in the Advanced-Misc section does something. It seems to have a modest affect on the APU1D and a fairly detrimental affect on the APU2C4.
Second, the APU2C4 only has about 73% of the performance of the APU1D using a single core and no hardware acceleration.
Third, the APU2D4 seems to excel in some circumstances and bomb in others. I expected to see a fairly consistent trend, but the charts seem to say otherwise.

Does anyone know which number is most representative of performance when running the openssl speed test? From what I'm seeing it appears that on the APU1D with aes-ni disabled we should be able to get 108MB/s on aes-128 with an 8k block size and 65MB/s on aes-256 with an 8k block size. It also appears that with the APU2D4 we should be able to get 567MB/s on aes-128 with an 8k block size and 442MB/s on aes-256 with an 8k block size. Those don't seem right to me. Can anyone care to elaborate?

Also, I've attached a screenshot of the spreadsheet I've put together with basic heatmaps. All values are the same and "are in 1000s of bytes per second processed". I just dropped the "k" so I could run calculations. Also, the commands that were run that include the multi switch were run as "multi 2" on the APU1D and as "multi 4" on the APU2C4.

Edit: I should note that these are all run with powerd on set to hiadpative. Also, added APU2C4 numbers that were forgotten.

The average I get running iperf across the LAN interfaces is:
APU1D -> APU2C4 = 235Mb/s
APU2C4 -> APU1D = 218Mb/s
APU1D -> Core2Box = 121Mb/s
APU2C4 -> Core2Box = 222Mb/s

Services enabled on the APU1D and APU2C4 in case they affect things are:
Squid
SquidGuard
AV Integrated in Squid
Snort
pfBlockerNG
darkstat
LightSquid

Are you guys using a full install or a nanobsd install on an msata 16gb ssd on an apu2c4?

Stewart

I'm running a full install.

kevindd992002

Without any modifications like using ramdisks for /tmp and /var? Fulll install as is?

Stewart

Yes. Using an msata ssd.

@Stewart:

Second, the APU2C4 only has about 73% of the performance of the APU1D using a single core and no hardware acceleration.

I saw similar results, back when I got my first APPU2. it seemed to be odd but then I re-ran the benchmark a few times and I always got more or less the same score each time…

Are the APU2 developers already aware of this? This issue seems to be a major one that needs addressing, right?

Qinn

I read there is a module for using the 3 front LEDs on the apu2 boards (http://pcengines.ch/howto.htm#gpio), has anyone using pfSense experience with this?

Thanks in advance,

Hi,

I just set up two APU2C4 boxes with pfSense 2.3.2. After a bit of fiddling with the USB stick for TinyCore, I managed to get it installed. On a 1Gbit connection, I had >800Mbit down and up through the firewall. No tuning what so ever.

I am using pfSense-CE-2.3.2-RELEASE-4g-amd64-nanobsd.img.gz

j4k3

Hey Guys, I wish I was getting maglub's performance out of the box.

I just received a APU2C4 in the mail and loaded pfSense-CE-memstick-serial-2.3.2-RELEASE-amd64 on it.

It manages to boot fine, and it's fully functional, the web interface moves much quicker and more fluid than the old ALIX2D3 it had replaced.

However when I run iperf on the LAN interface from another host, I'm only getting 300Mbps or so.

I found this thread about Intel I210AT nics and am attempting their suggestions:

https://redmine.pfsense.org/issues/1221

I see they're playing with the buffers and queues.

My question is this, if I edit loader.conf.local after looking at some of the options some options have "Quotes" around them, and others don't.

If I directly edit loader.conf.local when I specify variables in there, must they use " for the value? Or will just the value suffice?

hw.igb.num_queues="4" or hw.igb.num_queues=4 ?

Thanks

cwagz

I always use the quotes. I have not tried it without.

j4k3

Thanks for the insight, I managed to finally get close to 1Gbps on the lan interface.

I had to uncheck Disable hardware large receive offload, and Disable hardware TCP segmentation offload

Under System > Advanced > Networking

Based on what I've read so far I know this unit won't route more than 500 Mbps or so but I wanted to at least understand why, the nic was so hobbled right off the bat.

cwagz

I am looking for some opinions on downsizing my current pfSense system with an APU2C4.

Currently I have:
Supermicro A1SRI-2558
8GB Ram
120GB SSD
Akasa Fanless Enclosure

There are 6 people in my house and 30 or so devices. I am the only person that ever uses OpenVPN and it is usually from a mobile device on LTE so OpenVPN performance is probably not a huge deal. I run Squid and Squidguard to proxy the internet for my kids. Our internet connection is FiOS 150/150 Mbps.

It seems like I could build an apu2c4 and sell my current hardware. I would probably have money left over and a smaller, slightly cooler running device for pfSense.

Do you guys see any potential performance issues or reasons why this is a bad idea?

Does anyone know of a way to enable TRIM support on the SSD without having to boot of a recovery device? Is there some sort of tunable where it can be enabled on the next reboot?

I switched from A1SRI-2758/8GB to apu2c4 as I need the 2758 for another server.

Running iperf3 between two pcs connected by the apu (pfsense 2.3.2) I get
600Mbit/s in one direction
615Mbit/s in the other one.
CPU runs at 25% load, e.g. one core is maxed out.

I probably see different speeds because I already imported my old firewall rules and have three rules on one nic and around 20 on the other one.

I observed the same speed & load when I installed debian and configured a few iptable rules.

Adding more clients (iperf -P 8 ) gives me:
940Mbit/s direction a
690Mbit/s direction b
880MBit/s duplex

Enabling (disabling unchecked) segmentation offload gives me
940Mbit/s direction a
695Mbit/s direction b
940Mbit/s duplex
CPU runs at 85%

Speedtest (init7) shows me 930down/940up. Initially I got 720/920 & 670/920 but that was because of my slow laptop (sigh). Restarting firefox gave me consistent speeds around 940.

So I can route a single TCP connection at 600Mbit/s per core. One could probably achieve higher speeds by tuning ISR related configs but as I can saturate my gigabit line with multiple connections I won't change settings.

I set igb_numqueue to 4 and mbuf to 1mio. Unknown if it had an effect.
Somebody suggested to set a rx/tx level (or queue? dont remeber) to 8k. That did not have an effect.
powerD disabled/enabled (hiadaptive) did not make a difference
