<p>Hello nice people on CentOS list,<br>
</p>
<p><br>
</p>
<p><span style="font-size: 12pt;">Default governor on CentOS 7 ppc64le </span><span style="font-size: 12pt;">OS bootup is "conservative" . This has about 20% effect on benchmark numbers, if you don't change the governor to ondemand manually (for specific benchmarks).
I tested this on our barreleye power 8 server.</span></p>
<br>
This even though kernel config is set for "ondemand" as default governor:<br>

<div>[root@Barreleye-1 ~]# cat /boot/config-3.10.0-327.el7.ppc64le | grep -i ondemand </div>
<div>CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y</div>
<div>CONFIG_CPU_FREQ_GOV_ONDEMAND=y<br>
</div>

I filed a bug on this with details and am posting here for info and also to accelerate some response on the bug:<br>
