Increase CPU usage on HV after upgrade (7.2 -> 7.3)
Hello ,
After upgrading the system from CentOS 7.2.1511 to CenOS 7.3.1611 I
see that the average processing time has increased from 5-7% to 12-15%
(doubled). Not critical but it is not pleasant. Server as KVM with 5
virtual machines. Someone noticed something similar? If so, how to fix
that?
Thx.

If you have access to Red Hat documents you can look also here:

or in general some articles like this:

and to create pdf graphics with kSar
