@fmatthew5876, did you get anywhere with this? I'm having the same issues on the 40gbps adapters on Windows 10. It seems like something is not allowing the hardware offload to function on Windows 10, though I haven't figured it out yet.
Hey, thanks for this. As mentioned before I did not tweak anything. I just plugged it into a pci-e slot and rebooted the box. Windows 10 even already had drivers that just worked.fmatthew5876:
Intel has some conservative interrupt throttle values that kick in to limit CPU usage though. Did you tweak that with your X710 card? I tried with the X520 card.
Since I posted in this thread last time I actually get 9Gbps with my ConnectX-2 but only if CPU is idle. Just closing down software like MPC-HC helps for some reason even if video I'm streaming from LAN is on pause.
Firing up some real CPU demanding stuff like a video game makes throughput drop as low as 3Gbps.
Now I use a Intel X520 card (due to SR-IOV support out of the box) in the server and the ConnectX-2 in my desktop PC.
I think that with more pcie lanes the cpu works faster (lower latency), but I'm not sure if this is 100% right (TX, RX processing).but why they making this single port 10g cards in pci-e 8x ?
i'm still not really understand how 2.0 card will work in a 3.0 slot?
at 2.0 speed?
