New Alix board for 2013

- 50 concurrent iperf connections from PC1 to PC2
- 50 concurrent iperf connections from PC2 to PC1
Could you please show us your iperf command options so I could test it using a different brand of mSATA? I'm using Kingston SSDNow SMS200S3/120G and I never got any DMA errors using it even when I ran iperf.
I used to get the same DMA errors a lot on a x79 Chipset/LGA2011 CPU with Kingston SSDNow V300 Series SV300S37A/240G Drive connected to a SATA 6.0 Gbps port and running as squid AUFS cache. after changing it to diskd I rarely get them ever again. I also changed vfs.read_max=32 to vfs.read_max=128 and kern.ipc.nmbclusters to a value of 32768 but these two by themselves weren't enough.
I'm guessing it all has to do with drive & port transfer rate, but why would iperf saturate the drive in the first place? the msata16a is SATA II only (and performs lower than that) but the APU board ports should be using SATA III 6.0 Gbps according to AMD docs.

Don't have the exact command-history (i'm at home, test was done at office).
However it was something like:
server PC1: iperf -s -i 10 | grep "[SUM]"
client PC1: iperf -i 10 -t 99999 -P 50 -c 10.0.42.2 | grep "[SUM]"
server PC2: iperf -s
client PC2: iperf -t 99999 -P 50 -c 10.0.42.237 -

ZFS is completely off-topic, plus not used at all… someone perhaps might mute the stupid noise during boot.

but then it states SATA 6Gbps at the end…difference between AHCI and legacy IDE should give you around 15% performance boost not much more so not sure what is wrong here.
Is there a way to benchmark drives under pfSense?
Thanks.

I've actually considered making it more, rather than less present in pfSense.
But go ahead, keep on keepin' on about things.

Well if nothing else you could just dd to null to get an idea of sequential transfer speed.

Merely pointing out there's a noisy, scary, confusing, misleading warning making people do completely unnecessary "tweaks" .
As for making it more present - not interested in "cool factor" stuff. This is a firewall/router and the thing eats RAM for lunch. Geez. ::)

Not that I would need blazing speeds on a pfSense router, but today I tested SSD throughput on the APU for the above mentioned
ad4: 15258MB <supersspeed s328="" 16gb="" v4629=""> at ata2-master UDMA100 SATA 3Gb/s</supersspeed>with
dd if=/dev/zero of=/tmp/delme bs=12M count=100; rm /tmp/delmeand I got:
100+0 records in 100+0 records out 1258291200 bytes transferred in 47.450329 secs (26518071 bytes/sec)which is really bad.

What SSD is that?
-
That is the one sold by PC Engines
http://www.pcengines.ch/msata16a.htm
I read a review of the APU and this SSD and the guy at ipfire,org got the same bad results. He also states, that it is a cheap SSD and would buy another. http://planet.ipfire.org/post/pc-engines-apu1c-a-review

Yeah that's just down the the SSD itself rather than the board then, and it's pretty much what I'd expect for an SSD in that price range.
Read speed is far better than write speed though, and TBH I'm not sure what you'd want to be constantly writing at high speed to a small SSD like this for anyway, not least because of the limited write cycles of NAND.

Anyone else having issues bridging the LAN interfaces? I get intermittent connectivity when I try and I can see the physical connection dropping. It should be noted that as soon as I remove the bridge I no longer get connection drops.

SpankIt, are you using 2.1?
This has been fixed in 2.1.1. There is a long thread about it somewhere.Steve

Hi there!
I have an issue with APU1C and pfsense 2.1, the LiveCD is not booting. Here are more details:
Booting stops after "Starting the BTX loader" message.http://pcengines.info/forums/?page=post&id=2ADF62BD-420D-447D-A387-A9B047776417&fid=40251191-FF24-48A8-BB0E-995B04812ADE
Anyone has an idea what's wrong?
Bye

Marama,
I didn't try to install from CD, instead I'd recommend to install via USB-Stick. Choose the amd64 memstick-image and follow the instructions to write the image to the stick. Mount it with a running freebsd and append 'console="comconsole" to /boot/loader.conf (don't forget to mount the stick and change the filepath - this is not copy & paste):
$ echo 'console="comconsole"' >> /$USB_MOUNT_POINT/boot/loader.confNow you're good to go. Boot from the USB- Stick and pass the following line to the kernel during startup:
$ set kern.cam.boot_delay=10000Now you can follow the install-scripts as described in various How-To's.
If you want to use an SD-Card, it's even simpler - just follow the instructions from the CF-Card install to the letter, but during first boot pass the
$ set kern.cam.boot_delay=10000line to the kernel, and everything works as expected. Once booted it's best to add the "kern.cam.boot_delay" statement to /boot/loader.conf. Don't forget to remount the partition before editing, it's readonly per default.
Have fun!
-
Interrupt the boot loader.
type-
set kern.cam.boot_delay=10000
boot
After booting add kern.cam.boot_delay=1000 to /boot/loader.conf.local via edit or from console.sir could you please explain this further? how to do it etc..thanks

…Keychain, thanx for helping me out, but reseting from 115200 to 9600 seemed to have helped.
BTW, should I go for symmetric or embedded kernel? -

It's been covered several times, most recently by keychain, but to make the process clear:
Write the nano image to the SD card using a card reader and physdiskwrite.
Connect a null modem cable to the serial port and use putty or similar to connect at 9600.
Power the unit up. You will see a bunch of garbage due to the console being at the wrong speed.
Eventually, you will see pfSense booting. When you see a message about 'Booting [/boot/kernel/kernel]' press CTRL-C until it drops to an 'OK' prompt. If you miss it, shut down and try again.
At the prompt type:set kern.cam.boot_delay=10000Then press enter. It should return to the OK prompt. Then type:
bootand press enter. The unit should now boot. Assign interfaces. Remember re2 is the one marked 'LAN'
Log in to the webgui and go to diagnostics, edit file.
Enter:/boot/loader.conf.localin the save/load path. Then enter:
kern.cam.boot_delay=10000below and click the save button.

I am using 2.1, thanks for the heads up I will give that a shot.
