Homeplugs (ethernet over power) are fine for some things, but they add so much latency to the network.
Wired is so much better.
I did switch from homeplugs to mesh wifi. The difference night and day. Less latency, faster and overall more stable.
I arrived at that conclusion because my servers were using a NAs as storage for most services, all of them separated by homeplugs.
When I relocated the NAS with the servers, everything went smoothly so yeah. Removed all of that and used mesh wifi instead (because the line for internet isn’t in the same room as the servers)
