I believe I have seen the same thing with a Mid 2015 11,4 running catalina. Not diagnosing further because I could not find a reason for it fast enough and not sure if it really had an impact at the moment…. but could you try the following
sudo sysctl net.link.generic.system.hwcksum_tx=0 sudo sysctl net.link.generic.system.hwcksum_rx=0 sudo ifconfig en0 -rxcsum
Thanks, I'll have a sniff.
If you have some specific tests to run I would be willing to run them here on Big Sur with the same laptop but I have nothing now that runs Catalina
One of my mates found the same issue on Big Sur (beta) on a 2013 MacBook Pro. Just a simple mtr test to your local home router's IP address should, over wi-fi, should show you the jitter. Mark.
