High use of network and cpu after a snapshot recovery of with Btrfs file system

When I restore a snapshot of Btrfs, even a few months, snapd, rightly, updates all my snap applications.
My problem is:

  1. High CPU usage immediately after startup;
  2. High network use immediately after startup;
  3. I have no visual information that the snaps are updating.


  1. Visual information when a snap application updates itself;
  2. delay the update of the snap if at that time I need the whole network and cpu;
  3. Changelog to see the changes of the update, as APT does: apt changelog application
