How Processor Core Count Impacts Virtualization Performance and Scalability

xeon_d_rgb_3000.pngDriven by Moore’s Law, CPU architectures have advanced rapidly over the last decade. We’ve moved from discussing server performance purely in terms of GHz to a discussion where parallelism and the number of cores and software threads have become more important to achieving optimal application performance.

As virtualization has become more pervasive, two frequent questions are:

  1. What’s the best way to use all available CPU resources?
  2. How can we use benchmarks to determine the optimal configuration instead of having the simplistic view of using the amount of GHz and number of cores, particularly when comparing different architecture generations?

A new white paper looks into these challenges and also addresses the migration path of the virtual machine (VM) footprint re-evaluation during migration. Download it here.
