There are many benefits to virtualization, but a key aspect of fully realizing those benefits is ensuring that everything in your data center is performing well. The virtual infrastructure is a complex system made up of many parts -- the hypervisor, VMs, servers, storage, applications -- and if even one of those parts isn't firing on all cylinders, it affects the rest of the infrastructure. As such, it's essential to not only understand what affects virtualization performance, but also how to actively improve performance and successfully troubleshoot any issues.
With this guide, you'll be better equipped to anticipate and prevent virtualization performance problems. Below, you'll find information on how CPU and memory affect performance, how you can benefit from VM performance benchmarking and how to pinpoint application performance problems in a virtual data center.
What factors can affect virtualization performance?
Before you can take steps to improve performance in your virtual environment, you need to understand what elements affect performance in the first place. In this section, learn how different variables affect hypervisor and VM performance, with tips on testing and configuration.
