Benchmarking Code

• The Basics

The Basics

When making changes to your code, it's helpful to know the performance impact of your changes. Laravel provides a simple class to help you time code execution and check memory consumption. It's called the Benchmark class and it's a breeze to use.

Using Timers

To start a timer, simply call the start method on the Benchmark class and give your timer a name:

Benchmark::start('foo');

Pretty easy, right?

You can easily check how much time has elapsed (in milliseconds) using the check method. Again, just mention the name of the timer to the method:

echo Benchmark::check('foo');

Checking Memory Usage

Need to know how much memory is being used by your application? No problem. Just call the memory method to get your current memory usage in megabytes:

echo Benchmark::memory();
