In the context of system performance evaluation, a benchmark is the process of measuring and comparing the speed or efficiency of a program, algorithm, or hardware.
The goal of a benchmark is to obtain objective data on how quickly or efficiently the system operates when performing specific tasks. This helps identify bottlenecks, compare different implementations, and make optimization decisions.
Example: In Go, you can write a benchmark for a function to measure its execution time:
func BenchmarkMyFunction(b *testing.B) {
for i := 0; i < b.N; i++ {
MyFunction()
}
}
Here, b.N is the number of repetitions, which is automatically adjusted for precise timing.
Therefore, a benchmark is a tool for quantitative performance assessment.
