Benchmark Design: Choosing Between Open- and Closed-Model Tests

When designing a benchmark, one of the most important aspects to determine is how to best represent the use case with a load test tool. The two most common methods derive their names from queueing theory: open model and closed model.

This blog post will answer these two questions about designing benchmarks:

• Simply put and with commonplace examples, what are open- and closed-model use cases?
• Are there other considerations to choosing between open- and closed-model tests?
