Proxmox NFS Storage Is Slow

[jdorny]

Ok so after a ton of debuging on Proxmox 8.0.3 with slow nfs storage performance here is what I found:

Setup 3 nodes 10Gbe network
Truenas server with mirrored NVME drives
iperf shows full 10Gbe between nodes

debian bare metal host on same network gets full NFS speed to truenas server nvme share roughtly 600MiB/sec

Observations / Question:
1. When a Storage device is setup for a NFS share (on the Truenas server) via the web gui and then from the actual PVE host shell you run fio test against /mnt/pve/<mount name> max speed is about 40MiB/sec.
2. When a NFS mount is created manually on the pve host via the shell (with /test mount point) to the same truenas server the speed is roughly 600MiB/sec

Any idea what I have not done correctly?

Updated tonight as well to latest pve version. No change. Also looked at /proc/mounts to see if my temp nfs mount had any different parameters the the ones created by pve in /mnt/pve.

Same parameters I'm stumped how can two nfs mounts with same parameters to same location have different speeds?

Thoughts?
