       - question: How long does it take for Azure Firewall to scale out?
         answer: |
-          Azure Firewall gradually scales when average throughput or CPU consumption is at 60%. A default deployment maximum throughput is approximately 2.5 - 3 Gbps and starts to scale out when it reaches 60% of that number. Scale out takes five to seven minutes.
+          Azure Firewall gradually scales when average throughput or CPU consumption is at 60%. It starts to scale out when it reaches 60% of its maximum throughput. Maximum throughput numbers vary based on Firewall SKU and enabled features. For more information, see [Azure Firewall performance](firewall-performance.md).

+          Scale out takes five to seven minutes.
 
           When performance testing, make sure you test for at least 10 to 15 minutes, and start new connections to take advantage of newly created Firewall nodes.
