View source for HFT:Check the current CPU Speed

==  Check the current speed of the CPU ==

The speed of the cpu in /proc/cpuinfo will report the default speed of the CPU.  If the speed of the CPU has been changed in anyway it may not be accurate.  This includes overclocking on the HFT systems

==  Get the current CPU speed ==

Install the package from yum:

<syntaxhighlight>
yum install cpupowerutils
</syntaxhighlight>


Use turbostat to get the current speed.  This is shown in the GHz column.
