Upgrade to 23.01 WAN speed halved

stephenw10

Anyone seeing this with a T520-SO NIC?

That's the only one I have on hand to test and, so far, I'm not seeing the same limitations. I can pass whatever the CPU will support, which isn't much in this crappy test box but it's well over 1G.

Any updates on this issue?

Since I upgraded from 2.6.0 CE to 23.01 Plus it does not seem that I can revert back to the 22 version or choose a “Development” option on the update page. How can I revert back or where can I download the 22 plus version?

stephenw10

If you're running on Netgate hardware you can open a ticket and request an older image.

If you are running on your own hardware and upgraded from 2.6 then it's not possible to reach Plus 22.0X.

A good test here would be to try a 2.7 snapshot if you can. That has the most recent drivers. If you still hit this issue there then it will be in 23.05 too.

@stephenw10 Did some testing now and the same problem applies to the latest development version "Current Base System2.7.0.a.20230417.0600"

stephenw10

Ok, that's good info. And that's using the T422-CR?

JensErling

@stephenw10 That's correct

Same Scenario with this chelsio

download is max at 400-450 (50%)
while uploads perform 100%

No speed issues to report here - using a Chelsio T540-SO-CR on the LAN side and Intel i210 on the WAN side.

Below is the set tunables I'm currently using for the Chelsio card:

hw.cxgbe.cong_drop="1"
hw.cxgbe.pause_settings="0"
hw.cxgbe.nrxq="8"
hw.cxgbe.ntxq="8"
hw.cxgbe.qsize_txq="2048"
hw.cxgbe.qsize_rxq="2048"
hw.cxgbe.toecaps_allowed="0"
hw.cxgbe.rdmacaps_allowed="0"
hw.cxgbe.iscsicaps_allowed="0"
hw.cxgbe.fcoecaps_allowed="0"

Hope this helps.

@tman222

Thanks for the info but it is only impacting the T4/5 CR variants without the SO.

Hmmm, that's interesting. As far as I know, the only difference are the offload capabilities of the regular CR vs. SO-CR cards (SO = Server Offload). If those offloading capabilities are enabled by default by the Chelsio driver in newer version(s) of pfSense has anyone tried disabling them explicitly to see if that helps the performance?

Redmine issue for reference:
https://redmine.pfsense.org/issues/9091

stephenw10

The TCP off-load stuff should have no impact on connections through the firewall, rather than terminating on it, even if it is loaded. But it's not loaded by default anyway.
It does seem like the -SO variants are not affected though.
Is anyone seeing this issue on an -SO card?

RobbieTT

Anyone looked at duplex testing in detail, given the halving at 5 GbE and 1 GbE?

@jimbohello

I too am seeing my download speeds halved using a Chelsio t-420 in 23.01. Upload speeds are normal. I also tried using the latest 2.7 and had the same issues. I am currently back using 2.6.0 with full speeds

darkreign2049

I am having this issue as well. I recently moved my LAN interface over to the second port on my CHELSIO T520-BT and was only getting 470 - 480 Mbps download. I have been scratching my head for the better part of a week trying to figure what was going on. I switched back to a 4-port 1Gb Intel card and speeds went back to normal.

stephenw10

Has anyone been able to test this in a FreeBSD 14 snapshot?

superbree

I see that 23.05 beta has been released. Has anyone tried it to see if this fixes the problem or if they're even trying to?

stephenw10

There are no changes to the cxgbe driver in 23.05 yet. I would not expect any difference.
The maintainer is investigating.

@stephenw10
Per comments on redmine bug, no change with 23.05

https://redmine.pfsense.org/issues/14207

stephenw10

It would very helpful if anyone hitting this can test a FreeBSD 14 snapshot. That would allow us to rule out any changes pfSense might be doing. It will also give the driver maintainer something specific to test against.

I spun up a FreeBSD14 VM on Unraid and it does not find drive for my T520-CR. It says no driver attached. I have attached screenshot of both boot log and pciconf.
