Performance tuning for 10gb connection
-
Hi Steve,
I am using Speedtest.net, I have setup a Ookla server on my public side of my network. now from my work I have been able to get speeds up 6Gbs directly to the speed test server from an iMac pro (the one with the 10gbT port), how ever that is pushing over a really busy NNI in our head room and since its T based it has to convert from copper to fiber, so it might be the best I can get coming that direction.
I am not sure I am reading this correctly, but the top 8 lines items that have CPUx in the STATE category all stay in the high 95's, with 2 dropping to the low 70's.
Tested with bumping my IP Input Queue from 1000 to 2000, then to 3000, is there a limit here? Also I noticed that I didn't have an entry for mbuf, so I put one in at 1000000 then tested with 2000000.
between all changed I saw some small gains in speed on the speed tests. still about 4.1 to 4.3

If you hit q during the test you can copy/paste the output here.
Really depends what those processes are.Steve

Hmm, that was whilst passing 4Gbps?
Definitely not a CPU issue then, hardly having to work at all there! In fact suspiciously low.

Yes that was about mid test on the download leg of the test, but it remains pretty steady through both tests.

Hi @dustintuft - I have also done some testing at 10Gbit recently, here is a thread on that topic:
https://forum.netgate.com/topic/132394/10gbit-performance-testing
Are you getting 10Gbit locally on your network? The hardware you have running pfSense should be powerful for you to get 10Gbit speeds across the firewall. It might be interesting to run some iperf3 tests and drop the MTU down to decrease the packet size and the get an idea how many PPS your hardware can handle (this will be a limiting factor).
Also, here is a helpful link for 10Gbit tuning:
https://fasterdata.es.net/host-tuning/Finally, do you have another host (or hosts) you can test the throughput with or just he Mac?
Hope this helps.
-
The problem with that or this say: https://calomel.org/freebsd_network_tuning.html
Is that they are setting meant for hosts. Most of that tuning is only applicable to TCP end points and not directly to a router/firewall.
Some of what's here is more directly applicable:
https://calomel.org/network_performance.htmlSteve

@stephenw10 - good point and you are right. I mainly pointed that out in case the hosts themselves needed some tuning. At this point it's still unclear to me whether the issue is with the firewall (i.e. it can't process enough PPS) or one of the hosts.
Having said that, there is some tuning that can be done on the Chelsio itself. Please see this page:
https://www.freebsd.org/cgi/man.cgi?query=cxgbe&sektion=4&manpath=freebsd-release-ports
IMHO, parameters worth tweaking to start include the size of RX and TX queues and disabling flow control (Pause Settings).
Hope this helps.
-
Yes lets see the output of
netstat -mandsysctl hw.cxgbe.Might also need the dev.cxl and dev.t5nex if they have individual settings applied or to check for dropped packets etc.

Hi @dustintuft - before trying to tweak parameters on the firewall, can you confirm that you can move 10Gbit between hosts locally on your network (e.g. by running something like an iperf3 test)? It would be good to know this info before troubleshooting further.
-
Doing a POC for Solutions Provider biz. @dustintuft is your lack of response that you fixed the issue and forgot to update the thread (happens to me) or figured out the testing gear wasnt getting to 10G either. Please keep this party going...
-
@mountainlion I ran into a wall, I have ran iprefs that show my switch and cards can achieve 9.8gb, but that is server to server, these are dell r710 with intel 10gb dual port SFP+ cards, but I can't get those kids of speeds through the firewall or through the firewall to a speed test server local to the public side of the firewall. I am still trying to tweak the card drivers, but I am very unformulare with linux drivers so I am afraid I am not making much progress.
-
So just to drill down a bit more... are you saying you ran iperf from the pfsense OS via cli to another server and got 9.8G?
But when you ran through the FW and presumably from LAN to WAN, you get the 4-6G?Or are you saying you had separate servers setup to validate the network underlay can support 10G, but all things PFsense come up short?
If the later, then perhaps a feature enhancement request? -
Yea the later is correct. I have been messing with this some more this weekend, and I think I have at least got to a state where I am happy with the results.
Tweaking the BIOS and disabling hyper-threading seems to have given me the performance I was looking for. Here is my current speed test results. Keep in mind the speed test server is local to my public side and its 10gb so I am not expecting to ever see a solid 10 result.
If I get more time I might dive into some of the driver tweaks suggested, but I am not sure that will end well since I am a novus at best.
-
Id be interested to see a more comprehensive breakdown of the tweaks you made and before/after results. I tweaked by old c2758 setup and am about to embark on the same on my new system. Specifically interested in the difference between hyper threading on/off.
