Random Thread - Anything Goes

VMQ enabled in-driver for Broadcom Gigabit controllers in Hyper-V would kill network performance for the guests. Disable it then a driver update would set it back on again.

Oh man, this is so freaking true it's not funny.

Ah, straight up fail then. I knew I prefer Intel NICs for a reason.

What blows my mind is the fact that the specifications for VMQ make it clear that 10GbE ports and silicon for tying in to the CPU cores are required.

Despite years of requests to remove that setting enabler/re-enabler Broadcom just ignored it.

Relevant from 2016: I hate VMQ
