# Struct Benchmarks

This is a contrived benchmark to illustrate differences between iterating over an array of type `[]T` and `[]*T` and how much it matters if we `range` over them versus index into them. See [this thread](https://forum.golangbridge.org/t/can-someone-kindly-eli5-the-difference-between-using-slice-of-pointers-and-slice-of-structs/34905) for more details.

## Running the benchmarks

After cloning the repository, `go test -bench .` should yield something like this:

```bash

goos: windows

goarch: amd64

pkg: github.com/DeanPDX/struct-benchmarks

cpu: Intel(R) Core(TM) i7-9700K CPU @ 3.60GHz

BenchmarkRangeStructs-8           499588              2332 ns/op
