The main factor that affects the performance of the BigFix Inventory server is the performance of the underlying infrastructure on which the application server and the DB2 database are running. You must ensure that the recommended requirements are met.

Important: The official hardware recommendations were prepared with assumption that the BigFix Inventory server is running on a dedicated physical server or servers. If virtual machines are used, the specified hardware (processor, RAM, or disk space) must be exclusively dedicated to those virtual machines – not shared with any others.
Even if you meet the recommended requirements, the application might work slowly because of issues with the underlying hardware. The issues might be caused by, for example, sharing resources with other machines within the virtual environment. You can run some diagnostic methods to ensure that the underlying infrastructure is in good shape.

Make sure that you configured the VM Manager Tool efficiently. For more information, see: Best practices for configuring VM managers.
