Performance Metrics
Analyze Test Configuration:
System JPEG Library Decode
DCT method: Float
OpenBenchmarking.org metrics for this test profile configuration based on 254 public results since 30 January 2013 with the latest data as of 8 August 2018.
Additional benchmark metrics will come after OpenBenchmarking.org has collected a sufficient data-set.
Based on OpenBenchmarking.org data, the selected test / test configuration (System JPEG Library Decode - DCT method: Float) has an average run-time of 2 minutes. By default this test profile is set to run at least 10 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 118.8%.
