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.
