Performance Metrics

Analyze Test Configuration:

System BZIP2 Decompression metrics for this test profile configuration based on 439 public results since 18 September 2017 with the latest data as of 8 September 2022.

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.
