Performance Metrics

Analyze Test Configuration:

Hackbench

Count: 32 - Type: Thread

OpenBenchmarking.org metrics for this test profile configuration based on 284 public results since 8 February 2018 with the latest data as of 22 March 2024.

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

Based on OpenBenchmarking.org data, the selected test / test configuration (Hackbench - Count: 32 - Type: Thread) has an average run-time of 9 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.
