VMware Update Manager (VUM) is a component of VMware Infrastructure that automates patches and upgrades of ESX hosts as well as Windows and Linux virtual machines. A new white paper, VMware Update Manager Performance and Best Practices (, is now available.

In this paper we discuss VUM 1.0 host deployment, latency, resource consumption, guest OS tuning, high-latency networks, and the impact of on-access virus scanning. We also provide performance tips to help customers tune the system for better performance.
