However, if you don’t have access to a reserved machine, you should close as many programs as possible before running the benchmark, minimizing the effect of other processes on the benchmark’s results.Īdditionally, to ensure more stable results, you should run the benchmark several times before recording measurements, ensuring that the system is sufficiently warmed up. When possible, you should use either a physical machine or a remote server where nothing else is running to perform your benchmarks. Therefore, we need to minimize the environmental impact as much as possible.
The effects of power management, background processes, and thermal management can impact the test results, making them inaccurate and unstable. Let’s get started! Setting the right conditions for benchmarkingįor benchmarking to be useful, the results must be consistent and similar for each execution, otherwise, it will be difficult to gauge the true performance of the code being tested.īenchmarking results can be greatly affected by the state of the machine on which the benchmark is running. To follow along with this tutorial, you’ll need a basic knowledge of the Go syntax and a working installation of Go on your computer. In this tutorial, we’ll introduce some best practices for running consistent and accurate benchmarks in Go, covering the fundamentals of writing benchmark functions and interpreting the results. Golang includes built-in tools for writing benchmarks in the testing package and the go tool, so you can write useful benchmarks without installing any dependencies. Benchmarking in Golang: Improving function performanceĪ benchmark is a type of function that executes a code segment multiple times and compares each output against a standard, assessing the code’s overall performance level. I'm currently working on my own products and teaching programming via my website freshman.tech.
