poor performance with dom0 on centos7
Hi All
it is possible to tune dom0/domU for better IO/network performance?
Since I have changed to Cenots7 dom0, I have a really poor IO
performance inside a PV VM.
I have already done what is described on
http://wiki.xenproject.org/wiki/Tuning_Xen_for_Performance
It is better now but still significantly worse than with centos6 dom0
my settings:
xen parameter: dom0_mem=1024M cpufreq=xen dom0_max_vcpus=2
dom0_vcpus_pin
xl sched-credit
Cpupool Pool-0: tslice=30ms ratelimit=1000us
