    Limit RAM used by ZFS?

    My 64GB RAM machine with ZFS seems to stabilise at 80% memory usage all the time for the root proxmox host. (Proxmox 6.2.4) I have several VMs running on top of it, all of them using no more than 20GB of RAM, so I suspect all the RAM usage is by ZFS on the root host. I've read several posts...

    container backup is slow

    On my Large container the pbs takes 25 hours now. The same contaner with backuppc (incremental, rsync) takes about 90 minutes. Backing up a VM image is fast. (Non-incremental backuppc take 12 - 40 hours.) It seems pbs could use a feature where files with old atime/mtime would be skipped.

    Storage Replication - Starts fast and then slows to a crawl, second dataset slow from start. Using another way to send snapshots goes full speed.

    Update: Believe this has to do with Wireguard VPN, possibly an MTU issue but the high speed going down to a trickle is very odd. If anyone has any insight would appreciate it. Kinda new to Proxmox built in replication but I am very familiar with zfs send / recv Testing out simple storage...
