The transition from 6 to 7, the migration was faster, now the migration speed has dropped noticeably, and Iperf shows a 10 GB channel.
Also i tried it and it didn’t bring any positive results."https://forum.proxmox.com/threads/v-6-4-live-migration-limitations.88348/"

Thank you for your help, it got better, but not always and not every node for every one. It is strange that at 6.4 I had a secure mode and everything worked quickly, the speed on any node was always up to 10Gbps. now it's always different. With what it can be connected? with the CEPH update?​
