Hi team, new FreeNAS user (FreeNAS 11-Stable) on new hardware for video editing needs. I am migrating from an ancient Thecus NAS. While I wait for the new disk order to arrive, I have built the system but am using retired but error free 3x 1TB disks and 1 x 2TB disk to experiment with.
I am having significant Read speed issues on FreeNAS. Write speeds are fantastic. The read speeds are 18 times slower than the writes.
A new and fast Windows 10 PC reports that between it (henceforth "the client") and the FreeNAS box ("the server"), 30 Gb of SMB file copies averages out as:
Writes to FreeNAS: 111 MB/sec. Very happy with that.
Reads from FreeNAS: Between 5 and 7 MB/sec. Unusable.
To be clear, this is not mbps. It is MB/sec.
As a comparison, a ~10 year old Thecus from the same fast PC (client) was giving me:
Writes: ~20 MB/sec.
Reads: ~40-60 MB/sec.
Obviously, something is very wrong with the SMB Read speed. I'm a FreeNAS noob and would appreciate suggestions. I cannot fathom how Reads could be 18 times slower than writes on anything.
Hardware:
I originally had LACP configured on FreeNAS and the Switch, and it was working great, but removed this (just using 1 interface for the time being now). I also had Jumbo frames configured on FreeNAS, the Switch and the PC (MTU 8000), but removed these too. No performance improvements. N.B. the 111MB/sec write test was conducted under the LACP/Jumbo config and has not been retested since they were stripped.
Switch is a Netgear GS724T, 24x Smart Gigabit Switch. The switch, FreeNAS server and client have all been powercycled.
I will admit I am struggling coming up to speed with ZFS and FreeNAS, so I stumbled for a while to get SMB acting with write access as I do not have a Domain Controller. Any pointers for where to look, or what to post here, are appreciated.
Kind regards,
Ent.
