Hi,

 

I'm using armbian on a FriendlyElec Zero Pi device as my wireguard server. This is a extremely cheap device and for this reason it was chosen since I don't need powerful performances.

 

It happened that I found a tutorial that switching the Congestion Control for BBR (mine says it is cubic), would allow me to experience performance improvements.

 

I'm not being able to change this parameter in my image already configured using: 

root@zeropi:~# sysctl -w net.ipv4.tcp_congestion_control=bbr

The output says: 

sysctl: setting key "net.ipv4.tcp_congestion_control": No such file or directory
net.ipv4.tcp_congestion_control = bbr

Using this command: 

sysctl net.ipv4.tcp_available_congestion_control

Outputs: 

net.ipv4.tcp_available_congestion_control = reno bic cubic westwood highspeed hybla htcp vegas nv veno scalable lp yeah illinois

As far as I understood, the BBR option is not available to be selected. And I really want to have it running in my setup.

 

Is there a way to enable this in my armbian in a way I don't need to start everything from scratch?

 

If the answer is NO, how should I proceed to have an image with this option enabled? If you have a step by step tutorial, it  would be very helpful, since I'm not an expert in building linux.

 

Thank you for your support.

Whenever asking for support please provide the output of armbianmonitor -u

Check if tcp_htcp and tcp_cubic kernel modules are loaded.

Since you are using either a 3rd party build or built the kernel package by yourself you should already know your way around and adjust the kernel config to include the modules mentioned above.

  

Uboot loader 2019.10

Not relevant but you missed to update U-boot to 2020.04 which is commonly built with the kernel package.

We can't possibly cover research and development on your behalf. More of it ...

I have no idea what is missing in the kernel but we will accept your PR to the kernel config https://github.com/armbian/build/tree/master/config/kernel. If you speed up, there will be a release in a week, two. And this functionality will come with an update.

Already enabled in master (CONFIG_TCP_CONG_BBR=m) at least since 5.4.41

requires modprobe tcp_bbr

 

Is it possible to update my running version to 5.4.41? Mine says 5.4.35, so modprobe returns an error.

 

@Igor, I have no idea on how to proceed with a pull request. Actually I am not a developer, but I would be happy to help with anything that I could.

 

It seems like enabling tcp_bbr with modprobe shall solve my point. Thanks for everyone that replied.

At this moment possible by switching to nightly builds but this is not recommend in production. Nightly images are our development builds where things sometimes just break and can remain broken for days. That branch is ... for testing, but currently its safe, since we are near to the release. Go there and go back to stable after the release ...

What should I add to sources.list in order to enable nightly images to be installed? Or to update to 5.4.41, another process should be performed?

hmm , recently it came to my attention bbr between both wireguard servers is doing a very bad job:

while westwood ( the one I used years back before bbr came ) is still performing OK ( while 150Mbit constant should be possible with bbr as I had in the past )

Just wondering is this related to the kernel or is there a hardware module not set in the H6 boards ( two are orangepioneplus and see similar speeds between opioneplus and neo2 )

Perhaps oneof you chaps have an idea?

hmm, this needs further analysis.

It appears if I upload from my side ( where I currently reside ) to my remote site I get awful upload speeds on the H6 ( and H5 ) : ( no congestion even set ) and no VPN even :

while on my windows pc it comes at least to 20Mbit, while 40Mbit is max ( and also reported to several "speed testers' on the net :

My latop is WiFi while H6 and H5 boards are wired to my router directly

 

 

 

Put a RPi4 next to it ( DietPi ) and all of the sudden indeed max speed ( 40 Mbit ):

just out of box, also reverted tweaks ( congestion etc ) on H6 board and reboot but nowhere near 40 Mbit, 

are there realtek driver issues in kernel 5.10 that cause this behaviour - I remember last month there were issues and things were held back  for Allwinner platform on 5.8

 

Must admit if I spin up another iperf3 half of speed is gained on Rpi4 but when that is happening spinning up yet another iperf restores this speed.

That looks to me some optimization is needed but I see different behaviour on the allwinner boards ... VERY STRANGE ...

 

PS: I am bypassing VPN on both platforms currently to see what is going on.

at this stage I have continuous 40Mbit upload ( RPi4 ) and other way round ( H6 or H5 board ) :  site to my Rpi4 disappointing speed using only these "tweaks"

using westwood as congesion control changes stuff somewhat as indicated earlier.

This makes me wonder "what is going on with TX ( and RX ) in the allwinner/ realtek driver ( RTL8211 ) , patch?

 

Again all these results straight over Internet, no vpn invovled yet ....

well I decided to bring in the r4s and flashed latest dev image ( 5.10.9-rockchip64 ).

Long story short .. using westwood both ways seem to be meeting my needs, using bbr to site is also fine - but from site to home bbr is rubbish 

below results:

 

- fresh dev image built r4s , connected to "  enp1s0 " and results below

this is directly over Internet, thus no VPN yet.

I really wonder what is going on as using H5/H6 allwinners give horrific results.

why uploading on the allwinner platform is limited ( though 150Mbit is fine with me )

tried my rockpi4a , similar results ( bad ) as H5 and H6. 

Once switched to legacy 4.4 kernel, things rock and faster results again.

really wonder what is causing this: patch, kernel realtek driver, both / something else : lost?!

bumped my OpiOnePlus H6 boards to kernel 5.12 and surprise surprise , BBR is working as it should again ...

I really wonder what was causing this as in kernel 5.10 and 11 I had to use westwood ( with cake )...

  

net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr

 

shows 250Mbit ( meanwhile line upgraded which is max upload speed )
