glibc bench

The GNU C Library project provides the core libraries for the GNU system and GNU/Linux systems, as well as many other systems that use Linux as the kernel. These libraries provide critical APIs including ISO C11, POSIX.1-2008, BSD, OS-specific APIs and more.

To run this test with the Phoronix Test Suite, the basic command is: phoronix-test-suite benchmark glibc-bench.

Performance Metrics

Analyze Test Configuration:

glibc bench 1.0

Benchmark: modf

OpenBenchmarking.org metrics for this test profile configuration based on 474 public results since 31 July 2019 with the latest data as of 25 December 2020.

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.

Based on OpenBenchmarking.org data, the selected test / test configuration (glibc bench 1.0 - Benchmark: modf) has an average run-time of 2 minutes. By default this test profile is set to run at least 3 times but may increase if the standard deviation exceeds pre-defined defaults or other calculations deem additional runs necessary for greater statistical accuracy of the result.
