reduce boot time in dell R620

Hello,

for reducing boot time in R620 I  have read in another post this solution:

"You can turn off the power capping option, which holds the cpu at the lowest frequency during post. You would use openmanage power center to do this. http://www.dell.com/us/business/p/dell-openmanage-power-center/pd

Turning off in system characterization in the bios misc settings will also help"

What is the openmanage power center? Is it a free application for managing the power of dell servers?

Are there any other actions that could be taken?

Thanks and BR/
