Upgrade to 23.01 WAN speed halved
-
OK, did some experiments. I set the interface on the AT&T side from auto to 5gb. Even restarted both pfsense and the AT&T equipment and still getting no more than half the speed I used to before the upgrade to 23. Setting both to auto (which they were both at on 22 and working fine up to 5gb speeds) will only get me a 1gb negotiated link every time. And with both manually set to 5gb, I get no better than half the speed I used to. I'm seeing a ton of interrupts on both interfaces on the x550-T2 in pfsense. Don't recall what that was like in v22, as I didn't really look at that when things were working great. Think I'm gonna fall back to v22 (gonna have to poke around about doing that, as I've not needed to undo an update in pfsense before), which despite not actually indicating link speed, worked great for performance. Here are a couple screenshots of both the interface on the AT&T equipment and the pfsense x550-T2.
-
Hmm, check the boot logs to see if the NIC is coming up with the expected number of queues.
There is also a sysctl you can use to set the advertised speeds available for link negotiation. That might allow it to negotiate at 5G correctly.
-
I have not had the chance to update the firmware on one of X550-T2's yet, but will do so and test on my end. For the time being, I kept both my Chelsio cards installed, did a fresh install from 2.6CE to 22.05 (and installed the 23.01 security patches) and the system is just running super snappy, WAN speeds full symmetrical 950Mbps.
Will grab another nvme SSD, update the X550 firmware, reinstall --> 23.01 and retest WAN speeds sometime this week to verify if it's my Nokia GPON ONT that is the issue with the updated drivers in 23.01 for the Chelsio (and potentially X550) and report back.
-
Are any of you using traffic shaping? I have a post in the traffic shaping forum about my speed being cut in half with traffic shaping. I turned it off and that solved my problem. Unfortunately, due to another (known) bug, I can’t turn it back on to do more experimentation.
-
Thanks for sharing. Unless traffic shaping is enabled by default on a fresh install (which I would assume No) then I am currently not.
-
@brachy33 Correct. It is not.
-
Can also confirm I am experiencing the same issue. I am running pfsense as VM on unRaid and passing through Ethernet controller: Chelsio Communications Inc T520-CR. I get half of my fios 1gb speed on Wan. Rolled back to 22.05 for now.

@stephenw10 Not the best expert at what it should be reporting, but here are the interface lines from the boot log:

That's fine, 4 Tx/Rx queues on each. More than enough to handle 5Gbps unless your CPU is extremely low power.
What CPU is it? Does it report the expected clock speed? -
@stephenw10 It's an i5-6500 with 8gb RAM running on a 256 NVMe. Under full load, the CPU doesn't break a sweat. Interrupts on the interfaces in the status screen continue to pile up. Any other things to check/tweak? May roll back to v22 soon so that I can get proper network performance back.

Thanks

If the CPU speed reported correctly by:
sysctl dev.cpu | grep freq?I've seen one report of another 6th gen CPU stuck at 800MHz.
Seeing interrupts on the interfaces like that is expected. If it's moving a lot of traffic that rate isn't that high either. It would be interesting to see how that value compares in 22.05 but I suspect it will be similar.

@stephenw10 Hmmm, CPU freq seems OK to me:
dev.cpu.3.freq_levels: 3200/-1
dev.cpu.3.freq: 1152
dev.cpu.2.freq_levels: 3200/-1
dev.cpu.2.freq: 1194
dev.cpu.1.freq_levels: 3200/-1
dev.cpu.1.freq: 1149
dev.cpu.0.freq_levels: 3200/-1
dev.cpu.0.freq: 1190And I wasn't aware of what those interrupt value should look like. Not something I ever really paid attention to when things were working well. :)

Yup looks like what I expect with speed shift support, which is new in 23.01.

Quick update. Installed a new X550-T2 card and flashed to latest firmware, installed and configured from scratch 2.60 CE-->22.05 with security patches-->23.01. WAN is connected to same Metronet GPON Nokia ONT and...full WAN performance is back. 950Mbps/950Mbps symmetrical.
Of course now...I'm seeing small errors IN forming on the WAN interface (I had this happening before with this NIC as WAN interface) but it's working at correct speeds. The errors IN on this card is why I went to the Chelsio T520-BT in the first place, and that card plays nice with my ONT, but the speeds were halved on 23.01 when I first upgraded.
Next step is to double check firmware on the Chelsio card, update Lenovo server BIOS to latest, then go through entire install process again and see if I can get the speeds on the Chelsio card to remain full-speed on 23.01.
UPDATE: With the system using the x550-T2 for WAN on 23.01... after a restart no more errors IN on WAN from GPON ONT! Almost 1TB of data transferred since that reboot and no errors on either WAN or LAN. Beauty!! Looks like 23.01 is gravvy.

Update on my side. I had a spare Intel nic i211 that I passed through to use for my WAN.
Did a fresh install, dropped my config on it and brought it up to 22.05. I was getting full gigabit speeds download/upload.
Upgraded to 23.01 and again WAN download speeds are cut in half. I am seeing half WAN downloads speed on both Chelsio and Intel NIC. The Intel nic is at least giving me full upload speed. Could it be something in my config? I don't have anything exotic. And it works as expected on 22.05.
-
Do you have any sort of traffic shaping in play? That's about the only thing that might affect it like that.
-
@stephenw10 no traffic shaping configured.
-
Just a thought here and no idea if this is valid. But when I did my reinstall from 2.6-->23.01 I did not use a config backup. I manually reconfigured all my settings vs using the backup config...just to test (also my network config is pretty simple).
Could there be something in your old configuration backup that's just not carrying over to 23.01 and causing issues?
-
I have a backup pfsense VM that I have on a spare poweredge server. It has the same config as my main server. I updated that to 23.01 and I get full 1gb upload/download. Only difference with main server is cpu and Broadcom nics.
My next step is to setup a new vanilla pfsense install on my main server to test my Chelsio/i211 nics.
-
I am also experiencing this issue on all interfaces of my Chelsio T422 after the upgrade to 23.01 iperf from pfSense to my Unraid boxes is capped around 460-480mbps same with testing from one Unraid box to another through different interfaces. Doesn't seem to matter if its a SFP+ or Gig copper port, I can't get over 480mbps.
I will probably have to roll back to 22.05 until this is addressed. Not sure the best way to do so as I didn't notice the issue until after I made some changes to my configuration while on 23.01
