Slow network in docker container

On one of my servers I’m having issues with networking in docker container hosted in lxd container. The connection speed is extremely slow. Using speedtest-cli tool I’m looking at download speeds around 0.02 Mbit/s, where from the lxd container hosting the docker I’m having 901.83 Mbit/s. I’m using clustering with single node and ovn network. Any idea on how I can debug it?
