Hi all,
First time posting here - very excited to meet all of you and hope you can help solve this issue that I'm currently running into:
Client side:
- OS: Ubuntu 16.04 LTS
- Motherboard: Supermicro X10DRi
- CPU: 2x Intel Xeon E5-2630v4
- RAM: 2x Crucial CT4K16G4RFD424A (128 GB total)
- 10 GbE NIC: Intel X550-T1 (directly attached) with IP address 192.168.100.114/24
Server side:
- FreeNAS 11.1-U4
- Motherboard: Asus Z87-Plus
- CPU: Intel i7-4771
- RAM: 16 GB
- 10 GbE NIC: Intel X550-T1 (directly attached) with IP address 192.168.100.111/24
I've run iperf on the 10 GbE direct connection and unfortunately my 10 GbE bandwidth stays under 3.3 Gbps. According to iperf, the 1GbE NIC bandwidth works as expected at just under 1 Gbps. I've tried tuning the MTU to 9000 and setting the FreeNAS tunables as described at http://45drives.blogspot.com/2016/05/how-to-tune-nas-for-direct-from-server.html with no performance changes.
Below are the iperf results from the client side (running either 1 or 4 parallel client threads):
Any help would be appreciated! Many thanks!
