Quickly test the performance of your Laravel app with the Benchmarking helper

With the release of Laravel 9.32 yesterday, a benchmarking helper was introduced, which is useful to quickly test the performance of certain parts of your application.

It works by passing a Closure that runs some code you want to benchmark and returns the time it took in ms:

1use Illuminate\Support\Benchmark;
2 
3Benchmark::measure(fn() => Post::find(1));
4// Returns time in ms.
5// i.e., 0.1ms

Additionally, you can pass an array of Closures and optionally configure how many iterations the closures should run:

1// Run each callback three times
2Benchmark::measure([
3 fn() => Post::find(1),
4 fn() => Post::find(5),
5], 3);
6 
7// [0.02, 0.03]
8 
9// Use keys
10Benchmark::measure([
11 'Post 1' => fn() => Post::find(1),
12 'Post 5' => fn() => Post::find(5),
13], 3);
14// ['Post 1' => 0.02, 'Post 5' => 0.03]

The Benchmark class has a dd() method which runs the above measurements wrapped with a dd() call, which will output the results to the console or browser and exit.

1Benchmark::dd([
2 'Post 1' => fn() => Post::find(1),
3 'Post 5' => fn() => Post::find(5),
4]);

Couple this update with the dd() file/line output, and you have some useful new debugging tools!
