Windows 7 (and later versions) offers support for hardware configurations that exceed 64 logical processors. These processors will be divided into so called "kgroups" by Windows operating systems. This can lead to problems for applications which rely on older kernel APIs for affinitizing threads inside a process, resulting in the process running on fewer logical processors than presented in the operating system for use.
We noticed that the following CPU is affected by this problem and Industrial HiVision runs into performance issues when installed on such a server:
- Intel Xeon E5 2600
These processors are e.g. used inside Hewlett Packard ProLiant Gen9 Servers, please refer to the following article for further information:

Other processors offering more than 64 logical processors on Windows 7 (and later) systems may also be affected by this problem.
