Benchmarking results for BMC Remedy Single Sign-on

This topic was edited by a BMC Contributor and has not been approved.  More information.

BMC Remedy Single Sign-on (RSSO) is a new product of the BMC Remedy ITSM suite. RSSO supports SSO integration of the AR Platform with other authentication products such as SAML.

This topic covers the first case of Remedy Single Sign-on (RSSO) 9.1 benchmark, where the RSSO is deployed as in independent service.

Test Environment

BMC built a dedicated setup for RSSO benchmarking. The following table describes servers in this setup:

Server Number of ServerMachineOS
Remedy RSSO server 9.11VM with 2 vCPU 8 GB RAMCentOS 6.5
Remedy AR server 9.01VM with 8 vCPU 12 GB RAMWindows 2008
Remedy Mid Tier 9.01VM with 8 vCPU 8 GB RAMCentOS 6.5
Microsoft SQL server 20121Physical machine with 20 cores 512 GB RAMWindows 2012

Note

All servers have LAN networking connections.

The following tables describes the BMC Remedy SSO server configuration settings that were used.

Testing Scenarios

BMC measured Remedy SSO server response time and throughput for the following scenarios:

ScenarioWorkload descriptionServer Authentication Rate
A540 users with every user login (and logout) once  in every 45 seconds12 requests/second
B540 users with every user login (and logout) once  in every 36 seconds15 requests/second

Note

  • Timings reported above are server response times, excluding web browser rendering time. Timings were taken by using Silk Performer timer which measures server response times of the following HTTP requests.

  • Give a VM with 2 vCPU, Remedy 9.1 RSSO uses only 7.5 percent of CPU resource  and achieves  0.6 second average server response time when the workload  is 12 Authentication requests per second.
