1GbE speeds over 10GbE connections? MacOS
I was wondering if anyone is having this same expereince. I have a new 626x, all drives filled, x-raid, connected to a Netgear XS708E 10GbE router, and I'm getting very slow speeds over 10GbE. Not ev...

I was thinking e.g. a 5400RPM hard disk in an iMac could be a bottleneck.
I agree that could easily be it. iPerf would measure just the network, so the disks in the NAS and the iMAC wouldn't factor in - so it would help isolate the cause.
Can you copy from the thunderbolt RAID array to the NAS? That's another way to take the imac disk out of the equation.

With Jumbo Frames finding the right MTU for your environment can take a bit of work. I'm not sure if/how well Jumbo Frames work with 10G.
Though they should work just fine, I see no need for them with 10G. So I would just turn them off, and use the normal 1500 MTU.
Also, if iPv6 is enabled in the NAS, try disabling it.
Please send in your logs (see the Sending Logs link in my sig). Is your Mac reporting a 10Gig connection to your switch or 1Gig?
Are you using CAT6A cables? If not you could try using those.
I emailed the logs.
I'm using Cat 7 calbles actually.
In my mac network utility it states a 10 Gbit/s link speed.
On my router all the lights are greenm which on the XS708E indecates 10GbE supposedly.
Thank you for your time.
