Hey all! Fairly new to this stuff and I have a question about performance.
I recently built a Truenas core system out of my old editing machine. I have 8x8TB seagate drives (4 are new Ironwolf disks, 4 are an older model, ST8000VN0002 disks which I previously used). They're in a RaidZ2 configuration.
Specs:
CPU: i7-4930k,
RAM: 32GB of Ripjaw DDR3 RAM.
Mobo: Asrock x79 extreme6
NIC: 2x Intel x540 T1 NICs (on both the server and my desktop)
Switch: Switch is the Netgear XS708E
Cables: Cat6 cables connecting everything, one 6 foot from server to switch, one 25 foot from the desktop.
I'm getting about 180MB/s max write speed from my SMB shares to windows, which seems normal. However my read speeds don't seem to be going above 220MB/s. I feel that the read speed should be much higher.
I did run an iperf test and got better speeds of 1.5gbit up and 4.2gbit down. I've also done smart tests on the disks and there seem to be no problems there.
I was told to check the management interface on the switch for error rates. It says port 1 had 6 CRC error packets. Not sure if that's the same thing. I also can't find anything that would indicate the connection is being limited somehow. All ethernet ports are set to full 10g (except internet), cable tester results came back ok.
Can anyone help solve this mystery? Any advice, suggestions, or thoughts are greatly appreciated.
