January 2, 20224 yr hi there. I just came across a weird issue with my network speed. I noticed that the file transfer to both of my my Windows machines is capped at around 500 Mbit/s. The weird thing is, the speed does not drop while docker is disabled. With docker disabled I get around 800 Mbits. I tested with iperf after a reboot in all directions, multiple connections also tested. Network speed drops to around 500 Mbits as soon as I start one docker container which is on the br0 network. It does not matter how much dockers on br0 I start. It seems like some kind of limitation kicks in at the moment when br0 gets used. My custom docker network for SWAG does not have that problem. It only happens when I start a docker with dedicated IP on br0. Tried to disable bonding, no effect. Unraid runs on a AsRock H310CM-ITX/ac Board with Intel Core i3-8100, 24GB of RAM, NVIDIA RTX3060 and Intel I219V NIC (onboard). Any ideas what could cause this? Thank you in advance!
May 18, 20233 yr Did you ever find a way around this? i'm finding a very similar issue where all networking is capped to about 500Mbit whenever the docker is running. Even if I put a container on host it's throughput is capped, if I set up a separate bridge on a different NIC it is still capped, if I speedtest on a VM on that bridge it is capped. if I disable docker it runs at line speed, used to be much faster. perhaps IPvlan VS MACvlan? I havent tried comparing that yet.
July 15, 20232 yr Old post but experienced the same. Was debugging slow samba speeds. You can see below at which point the docker service was enabled. Macvlan IPvlan made no difference. Any suggestions?
