Hi all,

I have a truenas box exporting NFS mounts to Proxmox.

Any ideas how to debug/rtfm a problem with truenas lagging like hell (both ssh hangs/lags and WEB-UI not even refreshing) when NFS traffic happens from my proxmox backup tasks....

Truenas is unresponsive for 2sec than ok... then again 2sec ssh freeze then ok...
Backup runs ok in the background (probably very slow though... as my truenas server runs 10Gbit on SSD nicely)
Its very weird, while the backup is running on the NFS mount (on proxmox) system goes crazy....

SMB full 10Gbit read/right from a Mac client seems happy..

Ideas?
