I recently moved from a non docker ubuntu 18.04 setup to a full docker 22.04 setup. I used to get a pretty consistent 95-105 MB/s in sab. I can’t seem to get more than 70 MB/s in my new setup. Both my usenet providers are setup the same and using 50 connections. I’d love to blame docker, but thought i see if anyone here has seen this as well. Any suggestions on what to look at?
Slow sab tips?

This could be the I/O overhead caused by docker while using NAT networking: stackoverflow.com/…/what-is-the-runtime-performan…

The article your linked is citing a paper from 2014. Seems hard the believe the network stack hasn’t been significantly reworked in 10 years. That being said I don’t have anything to refute this.
Does the above still apply if using a glutun VPN docker with other containers connecting directly to glutun?

That’s a large penalty, wow.

It’s huge for networking. VPN gateway (for accessing the VPN WAN over LAN) on the host is 20-40% faster than dockerized…
