Hi,
I'm new to proxmox and started my first backup to a NFS share (TrueNAS Server) via 1G NIC. However, the backup process takes a lot of time, because the network performance mostly idles at a few KiB/s and suddenly jumps to 117MiB/s (max Performance) only for a few seconds.

My Proxmox Server contains 2x 960GB Sata SSD (5% filled) and 1x Nvme 2TB (50% filled). The Backup contains all data from my server.
I never experienced this behavoir with my other SMB Shares on my TrueNAS Server, they are mostly at max performance.

Please tell me, how I can solve this problem. Thank you
