If TB is not enabled, check your anycodings_cpu BIOS/UEFI configuration. You'll need to install the cpuid tool anycodings_cpu but this doesn't require the anycodings_cpu intel_pstate driver. You can check if TB is enabled by anycodings_cpu executing the command: cpuid -1l6 | grep -i turbo When anycodings_cpu disabled it is not reported by the cpuid anycodings_cpu instruction. This should be useful to those working with Citrix XenServer for server virtualisation or as a platform for XenDesktop, CloudPlatform, Netscaler SDX or similar.Turbo boost doesn't require software anycodings_cpu intervention but it can be disabled (by anycodings_cpu the BIOS/UEFI or by the OS). So here you go: how to enable turbo mode, C-states and P-states I’ve also included some example logs and instructions on how to interpret the CPU frequency results you may see. Plus how to check it is enabled and investigate how it is behaving and a few known issues associated with Intel errata affecting Intel Nehalem and Westmere processors. I’ve put together a page on how to enable turbo mode, C-states and P-states. Intel® Turbo Boost Technology 2.0 automatically allows processor cores to run faster than the Thermal Design Power (TDP) configuration specified frequency if they’re operating below power, current, and temperature specification limits. Intel® Turbo Boost Technology provides more performance when needed on 4th generation Intel® Core™ processor-based systems. Some of the CAD applications and benchmarks are proving rather fond of a single core and can show improvement if you configure XenServer to allow the CPUs to use turbo mode.As Intel details on their own page:

One of tools I’ve been investigating to profile CPU usage is CPU-Z. I’ve also been working with a lot of CAD and 3-D graphically intense applications looking at optimal configurations for benchmarking of technologies like vGPU and GPU-passthrough. Recently I’ve been putting together a page of useful tools for system administrators and developers to understand and debug bottlenecks in a XenServer installation.
