Windows 10: Killer vs. Intel network cards performance

I happen to have a family of three Dell machines in the house - a new arrival XPS 9360, an old beast Precision M4800 and an "aspiring" Inspirion 5667.

The new XPS 9360 is equipped with the Killer 1535 wifi card while the old models came with Intel cards. I've run tens of speed tests and it's certain for me that the Killer card's performance is constantly 20-25% lower than those of Intel's cards (all cards with the newest drivers available).

Has anyone done similar tests or come across Killer performance issues? There are lots of similar threads on Killer cards, and they are generally not really appreciated, but I'm seeking their comparison vs. Intel cards.

Windows Task Manager doesn't display network ultilization properly

I currently use Windows 10 with a Intel Wireless-AC 8260 and a Killer E2200.

Recently, after updating the drivers of those to the latest version

8260: driver 18.32.0.5

killer e2200: driver 8.1.0.31

the wireless ac is properly connected to the wireless network, the killer e2200 is not connected

it seems that the system is only watching the network utilization of the e2200.

i encounter the problem whenever i have killer's performance suite installed

i wonder if someone could tell me how i get the display proper

 

IRQL Not Less or Equal during Windows Update (Fall Creators Update)

I tried installing off of the Killer site as well, and it said that the Killer Performance Suite is not compatible with the Killer Network Manager Suite.
