Description

Performance problems can arise in any computing environment. In a virtualized computing environment performance problems can arise due to new and often subtle interactions occurring in the shared infrastructure. Uncovering the causes of those problems requires an understanding of the available performance metrics and their relationship to underlying configuration issues.

This document is a guide to performance troubleshooting for vSphere 4, including problems occurring on ESX 4 hosts. It uses a guided approach to lead the reader through the observable manifestations of complex hardware/software interactions in order to identify specific performance problems. For each problem covered, it includes a discussion of the possible root-causes and solutions. Topics covered include performance problems arising from issues in the CPU, memory, storage, and network subsystems, as well as in the VM and ESX host configuration. A forum exists at http://communities.vmware.com/docs/DOC-10352 for comments or questions about this document.
