Note: Benchmark results are measured in seconds.

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.
