Subject Label Legend: Attributes are determined based on the performance evolution of the workloads compared to the previous measurement iteration. NEUTRAL: performance did not change by more than 1% for any workload GOOD: performance improved by more than 1% for at least one workload and there is no regression greater than 1% BAD: performance dropped by more than 1% for at least one workload and there is no improvement greater than 1% UGLY: performance improved by more than 1% for at least one workload and also dropped by more than 1% for at least one workload Our lab does a nightly source pull and build of the Python project and measures performance changes against the previous stable version and the previous nightly measurement. This is provided as a service to the community so that quality issues with current hardware can be identified quickly. Intel technologies' features and benefits depend on system configuration and may require enabled hardware, software or service activation. Performance varies depending on system configuration.
