VM-Series on Microsoft Azure Performance and Capacity

—Many factors, such as the virtual machine size on Microsoft Azure, maximum packets per second supported, and the number of cores used, can affect VM-Series performance. In addition to those noted, the performance and capacities listed in the following table have been generated under controlled lab conditions, using the recommended Azure virtual machine size, and configured with Azure Accelerated Networking using SR-IOV and DPDK under the following test conditions:
  • Firewall throughput and IPsec VPN are measured with App-ID™ and User-ID™ technology features enabled, utilizing 64 KB HTTP transactions
  • Threat Prevention throughput is measured with App-ID, User-ID, IPS, antivirus, and anti-spyware features enabled, utilizing 64K HTTP transactions.
  • IPsec VPN performance is tested between two VM-Series in the same region. The performance will depend on Azure VM size and network topology, that is, whether connecting on-premises hardware to VM-Series on Azure; from VM-Series on an Azure VNet to an Azure VPN Gateway in another VNet; or VM-Series to VM-Series between regions.
  • New sessions per second are measured with 1 byte HTTP transactions.

VM-Series capacities specified in the page are not specific to Azure environments. For example, Azure Network Flow limits will limit your VM-Series session capacities in Azure.
Palo Alto Networks recommends additional testing within your environment to ensure that your performance and capacity requirements are met.
