This article provides throughput performance numbers for Versa Operating SystemTM (VOSTM) Release 22.1.4.

All throughput performance testing was done under the following conditions:

  • SD-WAN and CGNAT services with default configuration were activated during performance testing.
  • Testing was done with UDP traffic, as specified in RFC 2544, with a 0.1 percent acceptable loss rate, using 1024 sessions with application offloading and with CPU isolation enabled.
  • When you test UDP traffic, start the test with less traffic, and then increase by 20 percent until the service load reaches 100 percent.
  • For CSG350, CSG355, and CSG365 series appliances, and V110 and V120 appliances, QAT is disabled by default. This is based on a recommendation from Intel due to rare occurrences of traffic stalling when QAT is enabled.
  • The session timeout was set to high value (3,600 seconds).
  • Encryption with AES128-GCM, which is the default encryption method.
  • A Spirent tester was used for testing SD-WAN traffic (refer to Layer 1 traffic statistics).
  • Performance is the amount of traffic processed by the CPU; that is, it is an aggregate of WAN-to-LAN and LAN-to-WAN traffic.
  • Performance numbers were captured at 100 percent of the service load under ideal test conditions, so all numbers should be considered as maximum values.
  • The traffic test uses internet mix (IMIX) without fragmentation, so users may adjust the 1400 byte frame size in the tables below based on the traffic generator used for testing.
  • For devices using 16 or more CPUs, issue the CLI command set system service-options flow-balance-algorithm RR for idle session distribution.
  • Four or more physical interfaces were used, for optimal performance.
  • CSG5000 series and Dell-7515 appliances were tested with four 100-Gigabit Ethernet ports with eight pollers for branch-to-branch tests and sixteen pollers for DIA tests.

For all testing, the following internet mix (IMIX) distribution was used:

Frame Size (Bytes) Percentage
66 45
78 8
218 8
594 2
1354 16
1418 21

Versa CPE on AWS Instance

By default, AWS interfaces are SR-IOV capable. It is recommended that you use only SR-IOV capable interfaces.

AWS instances use a network I/O credit mechanism to allocate network bandwidth to instances based on average bandwidth utilization. They accrue credits when their bandwidth is below their baseline bandwidth, and they can use these credits when they perform network data transfers. For more information, open an AWS support case and ask about baseline bandwidth for the specific instance types that you are interested in.

VOS and traffic generator instances are in single virtual private cloud and AWS region.

All numbers need to be considered the maximum as claimed by AWS instance limits.

For items in the table marked with an asterisk (*), testing was limited by the AWS infrastructure or the VOS software.
