@Veldkornet congratulations, you posted an irrelevant performance number for people trying to configure a router or firewall!

offload can potentially help a client because the client can send a large chunk of data to the NIC at once and then allow the NIC to chop the data into packets and send. offload is useless on a firewall, which must inspect and process packets rather than large chunks of data.

VAMike

@FLOK 92.8Mbps looks suspiciously like you have something negotiating a 100Mbps link. even the original APU could push data faster than that, let alone the APU2, and with no faffing about with configuration settings. you are wasting your time by trying to fine tune your way out of this; put everything back to the default and then find the actual problem.

is it:

hw.igb.rx_process_limit="-1"
hw.igb.tx_process_limit="-1"

or

hw.igb.rx_process_limit=-1
hw.igb.tx_process_limit=-1

is "" needed?

Sorry

@Veldkornet

If you do the same setting as mentioned above, you get 1gbit

The setting from this speedtest was behind my current router (double nat), and the 3 tweaks applied which were mentioned in the post from @dugeem

Sometimes my speedtests seems to lock to around 700mbit or 500mbit, but i start to belive that this is an issue of my unit.
I also encountert a new behaviour. If I restart my APU2E4, im not able to access anything until i pull the cable from my wan port. Once the webinterface loaded, I can reconnect the wan and it works.
The same happens when i change the settings for TSO or LRO. Once i hit save, the system doesnt react to anything. Once i pull the plug out of wan, the webinterface loads in one or two seconds.
I start to belive that my hardware has an issue, I dont find any other explonation.

I've examined it and found the following:

iperf3 LAB
No matter if APU2/3/4 I get a throughput with single connection of 750-850Mbit/s (LAN 2 OPT)

With 2 or more connections I get about 945Mbit/s.

A Speedtest.net gives the value 934Mbit/s UP/DOWN

I have tested the following BIOS versions:
V4.9.0.2
V4.11.0.2
V4.12.0.1

All the same.

But what I noticed, tested on APU2 and APU3, that pfsense version 2.4.5 does not reach the same throughput as 2.4.4-p3.
With Single Connection pfsense 2.4.5 reaches "only" about 400-500Mbit/s. With pfsense 2.4.5 I can only reach 940Mbps with 8 connections.

@VAMike
Your message encouraged me to do research...
And you were so damn right.
My computer's stuck on the switch of an IP phone.
It throttles traffic to 100Mbits.

I am so sorry to have wasted your time :-(

I also noted something weird with 2.4.5.

My iPerf speeds were also much lower than normal. What I did to fix it was:

disabling hardware offload (check the check boxes)
save, no reboot (iPerf results the same)
re-enabling hardware offload (clear the check boxes)
save, no reboot (iPerf results back up to the expected levels)

The only thing I did between having good iPerf results and slow ones was reboot the device. It's as if after a reboot, it forgot that hardware offload was enabled, and I just needed to set it again.

@Veldkornet

pity this to argue further.... (LRO / TSO / etc.)
the forum is full of why you need to disable "offloading"

if you use pfSense for routing, (*****not recommended!!! *****), but just think of IPS netmap
******https://docs.netgate.com/pfsense/en/latest/config/advanced-setup.html#Networking

and @jimp https://forum.netgate.com/topic/42669/tso-and-lro-on-alix-boards

netmap it will not start properly unless they are disabled

all forum threads that belong here, it starts with this - disabling this features first -

DaddyGo

@kinch

let's wait for this 2.4.5-p1
but indeed we also experienced some difference, but not significant

just a suggestion instead of speedtest_net, I prefer to use this nperf.com
it uses a much more serious algorithm to saturate, ergo the measurement more accurate

"The only thing I did between having good iPerf results and slow ones was reboot the device. It's as if after a reboot, it forgot that hardware offload was enabled, and I just needed to set it again."

so,

enabling / disabling these functions will in any case require a restart!
without it it makes no sense, thus, the test is not relevant either

if the function is still active after a restart, this must be disabled with this way

/boot/loader.conf.local

hw.bce.tso_enable=0 or 1
hw.bce.lro_enable=0 or 1 ......... etc.

edit: bce / igb / etc.

test method after reboot:

ifconfig igbX | grep CSUM

X= 1 ,2, 3, 4, or........

Ha, I have done exactly that before.

@stephenw10
the joke is, that the pc still shows gigabit, although the performance is not reached

stephenw10

Ooo ouch. Yeah I didn't have that excuse.

Anyone running 2.4.5-p1 yet? Already on 2.4.5, so I don't think there would be much of a chance for something to go wrong...

Here running on 2.4.5_p1 - since yesterday and I cannot see any issue ...

Do you run ntopng on apu2c4 without problems on 200-300mbit lines (20mbit ish upload)? (I run pfBlocker, openVPN client and an openVPN server... mo snort etc)

Is this too heavy on the CPU?

Qinn

@daemonix I run Ntopng, no worries works good.

Hmm, strange here - i uninstalled ntopng because every time I saved the settings I got a core dump (but ntopng has continued to work).

Qinn

@fireodo In the past, Ntopng was slow, not to say very slow and I walked away from it, in the beginning of this year I tried it again and I was amazed how it progressed.

I am speaking from the newest version (0.8.13_5) and its the "core dump" what make me uninstall it - not the speed.
