The Jperf tests do show that if I change the buffer size from default to 16/32mb I'm getting fast transfers. The 1Gb is intended for internet access and 10Gb for internal nas/data transfer. There is also no transfer happening between the 1Gb network and 10Gb one. Its 2990WX based rig running M.2 as only drivers.

I simply installed windows on new workstation - now workstation is not your average pc here. New windows yields 100MB/DL and 300MB/UL. to put it simply TL R The hardware is not the problem, old windows yielded 800MB/DL and 300MB/UP. I'm not sure where the confusion is coming. Thanks all for help, will keep it posted if I figure it bro67 The new windows does not the only conclusion I can come with is that there is a setting buried somewhere that is messing stuff up. Old windows which was installed like 3 years ago worked quite fast out of the box with 10GB connection.

Seeing how often MS changers/tweaks TCP managment system. Seems to be latest -most up to date information. I also went over this post A word about AutoTuningLevel Hybrid Networking | Cloud and OnPrem No change :- TairikuOkami - I will check it out today. I was able to download at 700MB+ on old workstation and this one is even - I just run tests, Used this for guide : Changing the MTU size in Windows Vista, 7 or 8 (mtu, speed, windows, Windows 7, Windows 8, Windows Vista) Also how can it be cpu if I can upload to NAS at speed of 300MB but only download at 100MB ? Does not make sense.

I don't think its the CPU, as you can see on the other forum where I posted Jperf results. Maybe windows takes the test result from the 1GB internet network and applies to all interfaces, not sure.
