 ## Performance testing
 
-Before deploying Azure Firewall, the performance needs to be tested and evaluated to ensure it meets your expectations. Not only should Azure Firewall handle the current traffic on a network, but it should also be ready for potential traffic growth. It's recommended to evaluate on a test network and not in a production environment. The testing should attempt to replicate the production environment as close as possible. This includes the network topology, and emulating the actual characteristics of the expected traffic through the firewall.
