Yes. My another machine's interrupts are as follows:

Yes. My another machine's interrupts are as follows:

Hi everyone,
I faced the same problem as this URL:

Seems you bind the nic irq to second and third cpu for the bit mask
you set is 110, so now eth9's irq is working on the 3rd cpu.
Have you ever tried irqbalance service? It may help to balance irq if the
irq workload of 3rd cpu is too heavy.

The drop_caches mechanism doesn't free dirty page cache pages. And your bash
script is creating a lot of dirty pages. Run it like this and see if it
