System Performance Specifications
The performance capabilities of Cisco Secure ACS are largely dependent upon
the Windows server it is installed upon, your network topology and network
management, the selection of user databases, and other factors. For example,
Cisco Secure ACS can perform many more authentications per second if it is
using its internal user database and running on a computer using the fastest
processor and network interface card available than it can if it is using several
external user databases and running on a computer that complies with the
minimum system requirements (see System Requirements, page 2-2).
