# Performance Testing Performance testing consists of performing a variety of benchmarks on each function in the library. These tests are performed using the Google Benchmark library, and can be used to determine the impacts of a change during development or to compare builds. Please keep in mind that performance statistics are highly dependent on the platform on which they are run. The benchmarks provided here are meant only to give relative indicators of performance on the same system, and not as absolute indicators of what will happen on any system.
