Performance Metrics

Analyze Test Configuration:

RAMspeed SMP 3.5.0

Type: Scale - Benchmark: Floating Point

OpenBenchmarking.org metrics for this test profile configuration based on 3,293 public results since 6 December 2010 with the latest data as of 4 March 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.
