Also, it looks like the guys here updated their article but they are still insisting to enable all three HW offloads as they see that it gives better speeds.
Hi,
Because of the behavior of the TSO and LRO, it is important ...
This is an endpoint question and not a routing and / or a router NIC setup ...this will definitely help you understand the behavior (FreeBSD):

https://blog.cloudflare.com/how-to-receive-a-million-packets/TSO and LRO are not good, if you are a router, but if you are an endpoint you can use them...
remember you're talking about an APU (pcEngines) stuff and an i211 thing, you'll do more if you could increase your PCie bus speed and / or RAM
With such a MOBO, the opportunity is not given...
(dmesg | grep -i msi)which can help a lot, disabling EEE and FC on igb0-3
Something like:

Something like:
So are you recommending that TSO and LRO be enabled in this use case?
Also, I would really want to know what all those system tunables do before I implement them blindly to my system.
@dugeem any comment on this since you were the one who explained the routing concept for these parameters in the first place?

So we have been using APU4d4 stuff at the endpoints of our users and colleagues for years, so I can tell you first hand that their performance is finite....
The answer to your question is to never enable TSO and LRO on a router

this is an old thread, read my posts aboveBTW:
why do you think the TSO and LRO are disabled after a clean pfSense install (by Netgate) -

Yes, I'm aware that you are well-experienced with this boards. And I believe you. I'm just making sure that I'm running these APU2C4's to their max potential. And as you can see in my post yesterday, I have TSO and LRO disabled since early this year.
Also, I transitioned from using OpenVPN to IKEv2 IPsec and I can't believe my own eyes how fast IPsec is. I had to switch because I upgraded the Internet subscription of my remote site to 100/100. In any case, do you have any ideas on my question here?

Is it recommended to downgrade from 14.13.0.1 to 14.11.0.6 for the APU2C4 since it says on pcengines' website that the recommended firmware is the "latest 4.11.x.x"? Can you downgrade without any issues?
-
@kevindd992002 said in PC Engines apu2 experiences:

Yes, but you have to respect the correct flashing procedure.
Current BIOS is v4.13.0.2 so why downgrade? -
@fireodo where can I see the proper flashing procedure/order? And like I said, the only reason I'm considering downgrading is because 4.11.x.x is the recommended firmware as mentioned in their website.

fireodoAhh, I thought you were pertaining to an "order" of flashing when downgrading. So it's just the usual flashing procedure then? I'm using flashrom inside of pfsense. So I can directly go from 14.13.0.1 to 14.11.0.6?

You mean v4.13.0.1 to v4.11.0.6? If so yes, no problem, dont forget to interrupt power supply after flashing. (important to ensure a BIOS CMOS-Reset)
Regards,
fireodo -
@fireodo Sorry, yes, that's what I meant. And yes, I always make sure to interrupt power supply after flashing, for about 10 seconds.
Do you think it's still wise to downgrade though?

If everything work as expected you dont have to downgrade. The v4.13.0.2 has cleanup all problems that raised in the latest time - so if there is no trouble you dont need to down/upgrade.

@kevindd992002 I am for 3 days on bios mainline version 13.0.2 (don't use the legacy anymore) and no issues, IMO there is no reason to revert back to an older bios version and as @fireodo mentioned, whenever you upgraded to a new bios version you should power down the system. This is best done by going to the Diagnostics -> Halt System, wait for the system to power down, check if the power led is off, then remove the power plug, wait for 30 sec and then re-insert the power plug.

Ok, I'll just upgrade to 4.13.0.2 instead. And yes, I always do those same steps when upgrading the APU2 firwamre. I always gracefully shutdown/reset the APU2.

Another advise when you got the time. When you are still using UFS it is best to move over to the filesystem ZFS, this system can withstand power-loss better than UFS, as the APU2C4 has ECC memory which gives almost a 100% safeguard against bit errors.
Also recommend by Netgate https://docs.netgate.com/pfsense/en/latest/install/install-walkthrough.html

Way ahead of you on that, I already am on ZFS. I swtiched from UFS to ZFS a few years ago :) Thanks for the suggestion though.

Always follow the manufacturer's and BIOS developer's instructions, these are not stupid guys and are moving forward rather than backward

Not sure what you mean. The recommendation is 4.11.0.6.

Hmmmmm..
Yeah I know... (I see you are not an "old biker" with the APU MOBOs)
My friend this is an old web wording on the site (everyone runs into this) and the guys is messy and the site not updated...pls. subscribe to the newsletter and there are the latest infos, they told us a thousand times why it is not recommended the legacy / old BIOS
but you can also monitor the BIOS developments and ask the questions on GitHub..
the polish guys (3mdeb), super informatives, by contrast with pcEngines, they only answer the sales questions, hahaha
