Subject: iMX6 - CPU usage not able to achieve 100%

Hi,
We are using imx6Q custom platform based on sabresd platform for our
development with Linux 3.10.17_1.0.0-GA BSP.
We have checked the CPU usage using "top" command.
A simple test program running on a PC shows 100% whereas the same program running on this module (compiled with different compiler, of course) shows again 25%. Now, 25% is not hard limit, I have, albeit rarely, seen it to get to 33%, as well.
Why a single core does not usually go more than 25%?
Please suggest us. Thanks in advance.
Thank You,
Regards,
Ansari
