Hi,
Today I migrated a server form C6 to C7. The machine is dedicated for a
couple of redis daemons. given the traffic etc, we see cpu0 being 100% in
use immediately. No problem, had the same thing on the C6 server.
So I pinned certain processes/irq's to other CPU's and made irqbalance was
monitoring things. That did solve the issue in C6, but not this time.
The links below contain the output of /proc/interrupts. As you can see CPU0
doesn't seem that busy

The 2nd paste was about 60 seconds after the first one.
Am I missing something here? This is a brand new C7 installation:
[root@redis1 ~]# uname -a
Linux redis1.gamebasics.lan 3.10.0-229.1.2.el7.x86_64 #1 SMP Fri Mar 27
03:04:26 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Hardware is a brand new supermicro X9DRW board with onboard igb NIC's in
use.
Hope someone can help me!
