Hello CentOS Community,
So I bought a NIC (using the Intel 82579V chipset) that supports Dual RX and TX queues , my goal with that is so iam able to see and use two IRQs in /proc/interrupts and hence be able to take advantage of 2 cores on my CPU. Instead I only see one IRQ being used, and hence only one CPU core.. Please see below.
Advisement is appreciated!
Alex
