I have a set up of QNAP TS431X2 (RAID5 4x4gb IronWolf) connected to CSS326-24G-2S+RM (SwOS 2.7) via SFP+ cable (10Gb) and then I do have external router for internet connection on port 1 on CSS and teamed 2xLAN on my workstation (Win 7 pro) plugged in to port 3 and 4 on CSS.
Teamed adapter on workstation displays 2Gbps connection as it should.
In SwOS LAG recognise Trunk of port 3&4 and connected partner.
The issue is that I can not reach transfer speed grater then 1Gbps. My Teamed Lan adapters shows that only 50% of network utilization.
I am looking forward for any suggestions how to solve my problem and achieve full 2Gbps transfers on SMB.
