The server requirements for TEM Servers are located at http://support.bigfix.com/bes/install/serverreq.html. However, server performance and specifications can vary significantly depending on the details of the deployment (including number of agents, number of simultaneous console operators, number of Fixlet sites subscribed, number of actions, and so on...)
See below for example configuration for TEM Servers and databases. (Please feel free to add your own configuration information -- please include number of agents managed as well as other information about your deployment.)
