Performance Metrics

Analyze Test Configuration:


Internet Upload Speed metrics for this test profile configuration based on 540 public results since 26 March 2022 with the latest data as of 25 August 2023.

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.
