[Congestion Control]

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?

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.

Hi,

 

Here is the output of armbianmonitor -u:

Thank you!

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.
