Performance Metrics

Analyze Test Configuration:

Cyclictest 0.84

Test Case: clock_nanosleep TIME_ABSTIME, Interval 10000 ms, 10000 Loops

OpenBenchmarking.org metrics for this test profile configuration based on 187 public results since 18 December 2012 with the latest data as of 4 December 2022.

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

Based on OpenBenchmarking.org data, the selected test / test configuration (Cyclictest 0.84 - Test Case: clock_nanosleep TIME_ABSTIME, Interval 10000 ms, 10000 Loops) has an average run-time of 12 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.
