Updating table high processor utlization
Net* 2.0 or better, that will create performance counters that can be shown in the Perfmon program that is delivered with the Microsoft Windows* OS.Microsoft's perfmon is capable of showing many useful performance counters on the Windows* OS like disk activity, memory usage, cpu load.Figure 1: "CPU Utilization" measures only the time a thread is scheduled on a core Software that understands and dynamically adjusts to resource utilization of modern processors has performance and power advantages.The Intel® Performance Counter Monitor provides sample C routines and utilities to estimate the internal resource utilization of the latest Intel® Xeon® and Core™ processors and gain a significant performance boost When the CPU utilization does not tell you the utilization of the CPUCPU utilization number obtained from operating system (OS) is a metric that has been used for many purposes like product sizing, compute capacity planning, job scheduling, and so on.The advances in computer architecture made this algorithm an unreliable metric because of introduction of multi core and multi CPU systems, multi-level caches, non-uniform memory, simultaneous multithreading (SMT), pipelining, out-of-order execution, etc.Figure 2: The complexity of a modern multi-processor, multi-core system A prominent example is the non-linear CPU utilization on processors with Intel® Hyper-Threading Technology (Intel® HT Technology).For all of the above mentioned hardware counters on the Nehalem and Westmere based platforms, a corresponding perfmon counter is created and therefore all features supported by perfmon are also available for these counters like logging over time in a file or database.For Intel® Atom processors the perfmon counters for memory and Intel® QPI bandwidth and L3 Cache Misses will always show 0 for reasons mentioned above.
Using this daemon, it is possible to graph the various metrics in real-time.
More information about perfmon for Windows* 7 and Windows* 2008/R2 can be found at here (but perfmon has been available for many releases of Windows now).
Please read the Windows_file on how to install and remove the service for Intel® PCM.

Instead, we will contribute updates and new features to the fork Processor Counter Monitor on github.
