Optimization of VMs by NUMA

Introduction CPU & NUMA architecture

The main task of every CPU is to process data. But here is the misconception, the faster the CPU (or the more CPUs I allocate), the faster the data will be processed. This is unfortunately not quite that easy, because before the CPU can process the data, it must be read out by the slower system RAM and that latency can slow the CPU processing. In order to minimize the time the CPU is waiting on reading data, CPU architectures include on-chip memory caches (local RAM) that are much faster than RAM (the access is up to 95% faster).

Activation of Office365 through multiple Citrix Worker (Activation Token Roaming)

The activation of Office365 in Terminal Server environment is enabled with shared computer activation, but will not work without further configuration. What is not described in the Microsoft article, from my older blog entry, Office puts in the user directory “AppDataLocalMicrosoftOffice16.0Licensing” (the 16.0 stands for Office 2016, at 2013 there must be 15.0) a license token for the host (Server/Client). This token is valid only for the host on which the user has just activated the office. If the user logs on another host, a new token is placed in the directory.

For roaming profiles, the existing configuration must be extended by the folder listed above, or the folder that you defined with the GPO, so that it’s synchronized across all hosts.

Unlike the normal license token for FatClients, this is only valid for a few days. Microsoft has published this TechNet article: TechNet Shared Computer Activation
