SBRC System-of-Systems Performance Reference
This chapter provides performance summary results of tests to estimate the SBRC load in a given use case or collection of use cases on a given system-of-systems. You can break down the effects of the tests and use them as a baseline to make reasonable estimates of expected performance. The tests represented in this chapter are not exhaustive, but are intended to give an indication of scalability.
This chapter also covers the limits of hardware performance. For example, disk I/O is rarely a limit for performance other than local file accounting or logging, and is ignored in most cases. This chapter focuses primarily on the following key performance measures:
Overall CPU utilization (most relevant for SBRC)
Per-thread CPU utilization (most relevant for SSR D nodes), with a focus on the single-highest thread
Throughout this chapter, the results are preceded by an explanatory text. Front-end application is an instance of SBRC and back end usually refers to a D node running ndbmtd.
