tjbench is a JPEG decompression/compression benchmark that is part of libjpeg-turbo, a JPEG image codec library optimized for SIMD instructions on modern CPU architectures.
To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark tjbench.
* Uploading of benchmark result data to OpenBenchmarking.org is always optional (opt-in) via the Phoronix Test Suite for users wishing to share their results publicly. ** Data based on those opting to upload their test results to OpenBenchmarking.org and users enabling the opt-in anonymous statistics reporting while running benchmarks from an Internet-connected platform. *** Test profile page view reporting began March 2021. Data updated weekly as of 7 May 2024.
OpenBenchmarking.org metrics for this test profile configuration based on 83 public results since 24 February 2020 with the latest data as of 3 September 2021.
Below is an overview of the generalized performance for components where there is sufficient statistically significant data based upon user-uploaded results. It is important to keep in mind particularly in the Linux/open-source space there can be vastly different OS configurations, with this overview intended to offer just general guidance as to the performance expectations.
Based on OpenBenchmarking.org data, the selected test / test configuration (libjpeg-turbo tjbench 2.0.2) has an average run-time of 2 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 0.1%.
Notable Instruction Set Usage
Notable instruction set extensions supported by this test, based on an automatic analysis by the Phoronix Test Suite / OpenBenchmarking.org analytics engine.
Requires passing a supported compiler/build flag (verified with targets: skylake, tigerlake, cascadelake, znver2, znver3). Found on Intel processors since Haswell (2013). Found on AMD processors since Bulldozer (2011).
The test / benchmark does honor compiler flag changes.
Last automated analysis: 10 May 2021
