You can centrally govern and log all your traffic flows using a DevOps approach. The service supports both application and network level-filtering rules, and is integrated with the Microsoft Threat Intelligence feed for filtering known malicious IP addresses and domains.

 ## 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.

 Performance values are calculated with Azure Firewall at full scale and with Premium performance boost enabled. Actual performance may vary depending on your rule complexity and network configuration. These metrics are updated periodically as performance continuously evolves with each release.
 
-## How to configure Premium performance boost (preview)
+## Configure Premium performance boost (preview)
 
 As more applications are moved to the cloud, the network element performance becomes a bottleneck. As a result, Premium performance boost (preview) for Azure Firewall Premium is available to allow more scalability for those deployments.
 
-To enable the Azure Firewall Premium performance boost, run the following Azure PowerShell commands. This feature is applied at the **subscription** level for all Firewalls (VNet Firewalls and SecureHub Firewalls). Currently, Azure Firewall Premium Performance boost is not recommended SecureHub Firewalls. Check back here for the latest updates as we work to change this recommendation. Also, this setting does not have any effect on standard Firewalls.
-
-After you run the Azure PowerShell commands, an update operation needs to be run on the Azure Firewall for the feature to immediately take effect. This update operation can be a rule change (least intrusive), a setting configuration, or a Stop/Start operation. Otherwise, the firewall/s will update with the feature within several days.
-
-Run the following Azure PowerShell to configure the Azure Firewall Premium performance boost:
-
-```azurepowershell
-Connect-AzAccount  
-
-Select-AzSubscription -Subscription "subscription_id or subscription_name"
-
-Register-AzProviderFeature -FeatureName AFWEnableAccelnet  -ProviderNamespace Microsoft.Network  
-```
-
-Run the following Azure PowerShell to turn it off:
-
-```azurepowershell
-Unregister-AzProviderFeature -FeatureName AFWEnableAccelnet  -ProviderNamespace Microsoft.Network 
-```

 ## Feature flags
 
 As new features are released to preview, some of them will be behind a feature flag. To enable the functionality in your environment, you must enable the feature flag on your subscription. These features are applied at the subscription level for all firewalls (VNet firewalls and SecureHub firewalls).
