Sample Performance Benchmarks for Basic Service Virtualization

Last update May 3, 2017

The DevTest development team performed testing to show benchmarks for performance of service virtualization. You can use these benchmarks to help tune the performance of your system.

The following data represents a simple scenario to identify the behavior of VSE under heavy load. The variation of the independent variable has been limited to the payload size. Performance data has been collected for the following payload sizes: 1 KB, 10 KB, and 100 KB.

Environment Details

The following graphic pictures the topology of the Performance Lab.

Virtual Service configuration

Execution Mode Most Efficient
Think Scale 0
Capacity 20
Transaction type Stateless
Match Style Signature
Log Level


Other components: WARN

A single virtual service was deployed to the VSE. Each HTTP call produces a single transaction count in the VSE. There is no search and replacement activity involved in this transaction. The service returns an exact match response. Further processing is required neither at the requests nor the response level.

Duration of each test run: 60 minutes during off-peak hours

The data that are provided in the previous table represents the number of transactions that are handled by the VSE during each 60-minute test run.

System Resources Utilization

The following charts represent data that were captured from the VSE server machine during the execution of each test run. The machines hosting the database utilized a very modest amount of resources. The machine hosting the registry consumed limited CPU time (2 to 3%) and approximately 40% of the available RAM. Disk activity of the registry ranged from 50 to 100 KB/sec. This demonstrates that the machines supporting the VSE machine do not represent a bottleneck during the test runs.

    I believe we are missing the header in the results table in this page. Could someone adjust that, please?

      Cassiano - Sure, let me take a look.
