Recently I put together a useful tool page for system administrators and developers understand and debug bottlenecks in a system of XenServer. I also worked with many 3-D graphically intense applications CAD and watching optimal configurations for the comparative analysis of technologies such vGPU and GPU-passthrough. One of the tools that I was responsible for the investigation of CPU usage profiles is CPU-Z.
Some CAD applications and criteria are proving rather fond of a single nucleus and may show improvement if you configure XenServer to enable the CPU to use Intel Turbo mode.As details on their own page:
Intel® Turbo Boost technology provides more performance when needed on the Intel® core ™ 4th generation processor-based systems. Intel® Turbo Boost Technology 2.0 automatically allows processor cores to run faster than the thermal design power (TDP) specified frequency configuration if they are operating below power, current, and temperature specification limits.
I 'have set up a page on how to activate the turbo mode, C-states and P-states. Also how to check is enabled and investigate how it behaves and some known issues associated with Intel errata affecting Intel Nehalem and Westmere processors. I have also included some examples of papers and instructions on how to interpret the results of the CPU frequency you can see
So here you go :. How to activate the turbo mode, C-states and P-states
This should be useful for those working with Citrix XenServer for server virtualization or as a platform for XenDesktop, CloudPlatform, Netscaler SDX or similar.
