Benchmarks: VirtualCenter Database Performance for Microsoft SQL Server 2005

VMware published a new 12-pages precious paper describing how VirtualCenter performs when using a Microsoft SQL Server 2005 back-end database, and how it should be configured to achieve optimal performance.

The results are interesting:


The paper also includes some guidelines for correctly sizing the database, making it a must-read.
