Installation
To get the latest version of The Dragon Code: Benchmark, simply require the project
using Composer:
composer require dragon-code/benchmark --dev
Or manually update require-dev block of composer.json and run composer update console command:
{
"require-dev": {
"dragon-code/benchmark": "^3.0"
}
}
Using
Note
The result of the execution is printed to the console, so make sure you call the code from the console.
use DragonCode\Benchmark\Benchmark; Benchmark::start()->compare( fn () => /* some code */, fn () => /* some code */, ); Benchmark::start()->compare([ fn () => /* some code */, fn () => /* some code */, ]); Benchmark::start()->compare([ 'foo' => fn () => /* some code */, 'bar' => fn () => /* some code */, ]);

When measuring the average value among the results, when more than 10 iterations are used, the final data is filtered by peak values. The calculation of the 10% of the lowest and 10% of the highest values is excluded from the total result, thus the final data becomes cleaner and less dependent on any external factors.
Iterations Count
By default, the benchmark performs 100 iterations per callback, but you can change this number by calling
the iterations method:
use DragonCode\Benchmark\Benchmark; Benchmark::start() ->iterations(5) ->compare( fn () => /* some code */, fn () => /* some code */, );
If the passed value is less than 1, then one iteration will be performed for each callback.

total 0.2453 ms 0.1105 ms
------- --------------------- ---------------------
Order - 2 - - 1 -
------- --------------------- ---------------------
You can also get the number of the current execution iteration from the input parameter:
use DragonCode\Benchmark\Benchmark; Benchmark::start() ->iterations(5) ->compare( fn (int $iteration) => /* some code */, fn (int $iteration) => /* some code */, );
Without Data
If you want to see only the summary result of the run time without detailed information for each iteration, then you can
call the withoutData method, which will display only the
summary information:
use DragonCode\Benchmark\Benchmark; Benchmark::start() ->withoutData() ->compare([ 'foo' => fn () => /* some code */, 'bar' => fn () => /* some code */, ]);
Result example:
------- ------------------- -------------------
# foo bar
------- ------------------- -------------------
min 12.02 ms - 58.4Kb 14.71 ms - 55.4Kb
max 15.66 ms - 64.8Kb 15.67 ms - 57.3Kb
avg 14.65 ms - 60.1Kb 15.17 ms - 56.2Kb
total 73.93 ms 76.31 ms
------- ------------------- -------------------
Order - 1 - - 2 -
------- ------------------- -------------------
Note
If the option to display detailed information is enabled (without using the
withoutDatamethod) and more than 1000 iterations are requested, then the output of detailed information will be forcibly disabled, since there will be absolutely no point in it with a significantly increasing load on the computer.
Round Precision
By default, the script does not round measurement results, but you can specify the number of decimal places to which rounding can be performed.
For example:
use DragonCode\Benchmark\Benchmark; Benchmark::start() ->iterations(5) ->round(2) ->compare( fn () => /* some code */, fn () => /* some code */, );
Result example:
------- ------------------ ------------------
# 0 1
------- ------------------ ------------------
1 11.85 ms - 0b 15.22 ms - 0b
2 14.56 ms - 0b 14.94 ms - 0b
3 15.4 ms - 0b 14.99 ms - 0b
4 15.3 ms - 0b 15.24 ms - 0b
5 14.76 ms - 0b 15.14 ms - 0b

min 11.85 ms - 0b 14.94 ms - 0b
max 15.4 ms - 0b 15.24 ms - 0b
avg 14.37 ms - 0b 15.11 ms - 0b
total 73.47 ms 76.03 ms

Prepare Data
In some cases, it becomes necessary to call some action before starting each check cycle so that its time does not fall
into the result of the runtime check.
There is a prepare method for this:
use DragonCode\Benchmark\Benchmark; Benchmark::start() ->prepare(fn () => /* some code */) ->compare( fn () => /* some code */, fn () => /* some code */, );
When calling a callback, the name and iteration parameters are passed to it. If necessary, you can use this information inside the callback function.
use DragonCode\Benchmark\Benchmark; Benchmark::start() ->prepare(fn (mixed $name, int $iteration) => /* some code */) ->compare( fn () => /* some code */, fn () => /* some code */, );
You can also get the number of the current iteration and the result of the execution of the preliminary function from the input parameter:
use DragonCode\Benchmark\Benchmark; Benchmark::start() ->prepare(fn (mixed $name, int $iteration) => /* some code */) ->compare( fn (int $iteration, mixed $prepareResult) => /* some code */, fn (int $iteration, mixed $prepareResult) => /* some code */, );
