Hello there, got my first FreeNAS installed and could use help on slow SMB speeds.
I’m using 8x4TB 5400 HDDs in a Z2 config not using l2arc and ATM only 8 GB RAM. VDEV Sync = Standard. I tried Compression and Atime both on and off with same results.
The client is on a 1Gb connection, freenas on 1 pair of 1 Gb LAGG. Both machines connected to the same switch.
I’m getting between 2 MB/s and 20 MB/s via SMB share.
This is my dd results:
dd if=/dev/zero of=test.img bs=16M count=1024
1024+0 records in
1024+0 records out
17179869184 bytes transferred in 11.987456 secs (1433153890 bytes/sec)

FIXED
Turns out I have a bad SATA port on client-side mobo. Getting steady 110 MB/s via SMB.
