Using FreeNAS 9.3 (oldtimer but very stable) for NFSv4
Xeon CPU (12c/24t)
128 GB RAM
2 vdevs of 6x1TB SAS 7.2k drives
Intel P3700 PCIE for ZIL
Serving lots of small files (currently live 2 TB data in overall size) over NFS with aggressive NFS-clients.
Recently NFSD load began to be very high during peak hours, probably more demand for data.
And I wonder if 128 GB ARC is too small for 2 TB data?
(already made an order for 256GB RAM, maybe it needs more and plan a move to FreeNAS 11.1)
