Performance Metrics

Analyze Test Configuration:

Schbench 2021-09-09

Message Threads: 8 - Workers Per Message Thread: 4

OpenBenchmarking.org metrics for this test profile configuration based on 37 public results since 3 December 2022 with the latest data as of 1 November 2023.

Additional benchmark metrics will come after OpenBenchmarking.org has collected a sufficient data-set.

Based on OpenBenchmarking.org data, the selected test / test configuration (Schbench 2021-09-09 - Message Threads: 8 - Workers Per Message Thread: 4) has an average run-time of 4 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.

Based on public OpenBenchmarking.org results, the selected test / test configuration has an average standard deviation of 15.3%.
