@bmeeks Let me also add one other historical note..
Previously before moving to this hardware set, we were running a D525 1.8Ghz Atoms with 4GB Ram and 128SSD (I know.. way underpowered) but we were getting symmetrical 400Mb. (they used the intel em driver, not the igb driver). What prompted the change was ramping up the speed (and since we were rolling out VPN, needed AES-NI for more efficient connections and speeds).
At the time, I assumed the reason we could never crack above 400Mb was the system (D525's are fine for minor home use, but a heavily used 1Gb connection with TINC, IPsec, and OpenVPN connections and several outbound streaming services...that was just not going to cut it as a pfsense box). But to date, I have yet to crack the 400Mb barrier with pfsense.
I have not yet tried another system (mostly because I have a preference for pfsense (been using it commercially for a long time (since the 1.x days) and before that m0n0wall) so I'm mostly familiar with it.. and I find it to be faster than most linux derived systems (otherwise untangle would be on my radar). Love linux as a server (we have a lot), but for performance, I find BSD based systems to be better. I know my Cisco router can do the full 1G, as well as Ubiquiti Edge Router as well as Vyatta. (I tested with all of them before in this DC before moving our kit here..so I know the speed itself is good.. just have to figure out why my beloved pfsense is not doing its job.)
Try a test using
iperf
to check out the interfaces. There are many folks using pfSense for Gigabit symmetrical connections. In fact, during testing of Snort with Inline IPS mode on pfSense-2.5 the Netgate tester recorded 1.8 Gigabits/sec of sustained throughput. Without Snort running, that rose to 3.2 Gigabits/sec. So the software is certainly capable. That was three interfaces running on an SG-5100.Of course there could be an issue with a particular driver on the FreeBSD side. And since pfSense is based on FreeBSD any driver problems would show up. Don't know for sure about any identified igb issues, but then I don't keep up with that area.

@bmeeks I completely agree.. I did a lot of research before jumping in the forums and these days and 1G internet connection is passé. Its why I'm very puzzled.. (and why we tried a number of system tunes and other changes because I know the software is capable (based on many accounts) and I believe the hardware should be fine (since its basically the same hardware Netgate is selling for 10gb connections)
If I use a public iperf server (from internal client through pfsense to public iperf server (thankfully HE has one in the same DC I'm in), I get:

[ 4] 0.00-8.03 sec 886 MBytes 926 Mbits/secIs there a way for you to put something on the WAN side (another machine perhaps connected to the same switch) and do an
iperf
test through pfSense from LAN to WAN? The key is to be able to reliably eliminate any dependency on an external host. To really test the pfSense hardware and software you need aniperf
endpoint directly on the WAN network and the other endpoint directly on the LAN network.With that HE test, I suspect there are other hosts, routers or connections between you and them even if in the same DC. Just trying to make sure you test only pfSense itself. That's the only way to narrow down the problem.
Do you perhaps have another Intel server NIC that uses say the em driver that you could substitute for testing? It's certainly not impossible for there to be a software issue in the NIC driver for igb. However, if true and widespread I would expect to see a lot of posts here complaining. The igb driver is used by some of the NICs in Netgate's SG-5100.
-
Don't know if anything in this thread directly applies to you, and the hardware is likely some different, but here is a post from last year about igb throughput problems: https://forum.netgate.com/topic/133704/poor-performance-on-igb-driver/43.
And are the NIC ports on your board genuine Intel chips or are they a clone from another vendor? If not genuine Intel, that may be part of the equation to consider. I found some instances on a Google search where the HP clone of say the Intel i350 didn't perform as well with the igb driver as the native Intel card did in the same box.
-
Yeah you really need to just test pfsense here, and take the internet out of the equation completely..

So help us understand the path a bit better. Which IP is what device in the about output. I take it your second test was this way --
BoxA --> pfSenseLAN port
and you had an
iperf
agent on pfSense and BoxA. Is that correct?If the above is true, can you do the same thing on the pfSense WAN port. This will nail down if the issue is something on say the WAN port, or if there truly is a routing bottleneck within the pfSense/FreeBSD network routing code.
I don't see how we've checked the actual WAN port in the box yet based on the data posted above -- unless I'm missing some detail. You tested the LAN port and it looks fully capable. But what about the WAN port? Can you simply unplug the WAN cable from the firewall and put your laptop directly connected to the WAN port with a crossover cable? Give your laptop an IP in the WAN subnet and then run
iperf
again.And just for grins, try disabling the
pf
firewall engine. You can do that under the SYSTEM menus. That will turn pfSense into essentially a dumb router by taking all of the firewall code out of the path. That setting is under SYSTEM > ADVANCED and then the Firewall & NAT tab. It's a checkbox. -

Don't need a crossover, gig interfaces all support auto mdi-x
Just do the test please all the way through pfsense, doing nat and firewall..

Crossover cables are not required with Gb NICs. With 10 & 100 Mb, two pairs were used, one in each direction. With Gb, all 4 pairs are used for both directions.

@johnpoz If you look at my earlier comment you will see the result to that.

@johnpoz Don't need a crossover cable.. nor should one need. One can reach native speeds with all the requisite hardware and without pfSense as the FW.

@bmeeks I can do the last test when I get back to the DC.. but I think I mentioned earlier, that if I plug in directly to the DC line (no pfsense, just give my laptop a public IP, and start testing, I get native speeds.. NEVER have a slow down.. Its only when traffic is going through pfsense it gives me slow speeds.
I also before even installing pfsense, I ran similar tests with linux on the same hardware (had to make sure its sound before installing what will be OUR "core" Router/FW/VPN Server.) So I KNOW the hardware is good (at least under linux, Ubuntu Server 14.04, no tweaks, just patched up to what was current then and then installed iperf (and iperf3) and then started to test as a burn in and performance validator)

The only thing I've not seen proved here thus far to my satisfaction is whether or not the actual physical WAN port on the pfSense box has been verified to pass gigabit traffic flow. I don't doubt that you are not getting gigabit through the box, but we are trying to figure out why. Is it because pfSense itself just can't do it (unlikely, but never impossible)? Or is it because there is some weird issue with just the physical WAN port? I think you said earlier you had swapped physical ports around, but depending on how you are testing through pfSense you might still have had that "bad" port in the mix. We can't see your entire configuration so we have to make assumptions about some things. For instance, if you have just two ports on the box and you swapped LAN and WAN around that won't help as that would just swap the throughput problem from one port to the other. On the other hand, if you have 4 ports in the box and are only using say two of them and you swap LAN and/or WAN to the other ports that is a more valid test. Of course there could still be some backplane issue that ports shared. Wouldn't know that without digging into the details of the motherboard.
What we are all trying to say is that if you can connect two laptops or two other physical boxes directly to the pfSense NIC ports (one on the LAN and the other on the WAN) and then run an
'iperf
' between those two connected machines that will test just pfSense with no other variables. If that gives the same poor throughput, I would next try with thepf
firewall disabled. The last desperate test would be to boot the firewall box on a Linux distro live CD and do theiperf
test that way. If suddenly Linux has poor throughput as well, then something has gone weird in the hardware. On the other hand, if Linux works like a champ in the same connection scenario, then that definitely points the finger at pfSense or FreeBSD (more likely FreeBSD as the core network code is not altered all that much in pfSense).And lastly, I am assuming we are still using a plain-vanilla pfSense install with an empty firewall rule set and no imported previous configuration info. Just install pfSense, select interfaces, set IP addresses and then test.

@bmeeks Maybe I'm not explaining things clearly.. so let me try it this way.. my old friends, succinct bullet points and diagrams.
Current Hardware:
Supermicro RS-A2SDI-4C4L-FIO Intel Atom C3558 Networking Front I/O 1U Rackmount w/ 4X GbE LAN
8GB RAM
128GB SSDServices Normally Running on pfSense:
OpenVPN Server (4 Site-to-Site Client Connections to Japan, Taiwan, HK, and California) - Normally chews up about 2Mb on the pipe (will spike depending on what actions are taking place)
TINC (Mesh Network) for connecting VPC's (10 of these) - Normally chews up 1Mb on the pipe (will spike depending on what actions are taking place)
DNS Services - uses about 30Kb average
NTP (final time source for company) - uses about 5Kb average.I have a separate dedicated pfsense instance that handles client level VPN (running in a VM in our ESX cluster. the performance there is terrible as well, but 200Mb is adequate for client communication)
Previous tuning was based on the 1Gb tuning from here: https://calomel.org/freebsd_network_tuning.html. (had no impact on performance or stability).
This is the "typical" configuration that I have running all the time:
Servers <---> 10GB Cisco LAN SWITCH <---> igb0 [pfSense box] igb1 <---> Data Center Core Switch
Variants/Tests that I have tried (after each test, then reverted back to the above configuration):
[pfSense box but running linux] igb1 <---> Data Center Core Switch <---> Test Server (in the DC but not internet connected)
Purpose: To confirm hardware is solid. (did 24 hour burn-in test with this first before installing pfsense)Servers <---> 10GB Cisco LAN SWITCH <---> igb1 [pfSense box] igb0 <---> Data Center Core Switch
Purpose: to see if slow performance moves from WAN to LAN, which it did not. LAN was still solid at 1Gb speeds, and WAN still had the same performance (roughly 200Mb down and 400Mb up)Servers <---> 1GB Dell LAN SWITCH <---> igb1 [pfSense box] igb0 <---> Data Center Core Switch

I hope this clears up things.

I would try putting some simple unmanaged switch between the pfSense WAN and the datacentre core switch.
Whilst you were able to see 1Gbps from the WAN to the Coreswitch with Linux running on the hardware the FreeBSD igb driver might be doing something odd, or at least different. We do see that sort of thing occasionally, though usually with crappy SOHO routers.

Hi, I'm following along with this problem and was just wondering if an improper BIOS setting would cause this. Im thinking maybe enhanced C1E or ACPI T-states in the BIOS?

That could cause low throughput if the CPU is somehow stuck at it's lowest speed.
That might affect FreeBSD differently to Linux which would likely enable CPU frequency control by default.
But it would not produce the asymmetry in speed seen here. It would be limited equally (or close to it) on both directions.
Certainly worth testing enabling powerd if you have not though.
