Balancing CPUs intel 10 GB

Post by hugleo » 05 Apr 2017, 13:24

In my new server (NUMA) have one core reaching 40% and other cores 2%
Tried to solve using default intel default kernel affinity one txrx queue by core or Installed irqbalance and doesn't seen to work.

So I uninstall irqbalance and use a script to allocate interrupts for all cores.

Looks like maybe I can have more interrupts i don't know. But at least all cores are working balanced and now I see peaks at most of 15%.

I would like to share the script, hope be useful ;-)

for irq in `grep ens1f0 /proc/interrupts | cut -d: -f1`; do echo ffffff > /proc/irq/$irq/smp_affinity; done

for irq in `grep ens1f1 /proc/interrupts | cut -d: -f1`; do echo ffffff > /proc/irq/$irq/smp_affinity; done

for i in `seq 0 7`; do echo fffffff > /sys/class/net/ens1f0/queues/rx-$i/rps_cpus ; done

for i in `seq 0 7`; do echo fffffff > /sys/class/net/ens1f1/queues/rx-$i/rps_cpus ; done


Using Debian Stretch.
