So it appears like, for the last ~months, my MTU configuration was REALLY wrong
Hinted by the immich longhorn replica not rebuilding, but I also didn't know, the extreme slowness of any service using a db cluster where the master node wasn't in the same region
I had put the slowness on the shoulders of packets hopping a lot between regions, but it turns out, it was just db requests maxing past the configured MTU value, silently dropping
Now that BOTH the wireguard and flannel MTU values are set properly, everything is so damn snappy
This feels like new skin
