Troubleshooting Performance Related Problems in vSphere 5.0 Environments

Version 1
Visibility: Open to anyone
    The Performance Troubleshooting for VMware vSphere guide has now been updated for vSphere 5.0. This document provides a step-by-step approach for troubleshooting most common performance problems in vSphere-based virtual environments. The steps discussed in the document use performance data and charts readily available in the vSphere Client and esxtop to aid in troubleshooting performance issues.


    New sections were added to include additional performance troubleshooting steps and resolutions utilizing the new vSphere 5.0 Performance features. New sections include identifying and correcting performance problems resulting from power management, reducing the performance impact of VM memory swapping, improve storage performance by automatically monitoring and control storage workloads, and improve multi-cast networking performance utilizing splitRxMode.


    This document by no means covers the entire breadth of performance-related problems. We request the readers of this document, including VMware performance community members and vSphere administrators, to help us enhance this document by letting us know about all the performance problems they encounter in their vSphere-based virtual environments, including those that require elaborate troubleshooting steps.  We hope that the community will actively contribute by engaging in live discussions, providing feedback, and asking questions. All this input will serve as the topics for future updates.
