Benchmarks & How to properly bind a Singleton in the Laravel service container #10

Benchmarks using Laravel 9, PHP 8, (16 cores @ 3.60GHz)

Sorry for any bad formatting. This was just a quick test I did and thought I would share :)
Test 1: Initializing generator outside the loop
$zooIdGen = RobThree\HumanoID\HumanoIDs::zooIdGenerator();
while ($i <= 1000) {
$zooId = $zooIdGen->create($i);
echo $zooId . '<br>';
$i++;
}Result: 10 000 loops took 1.3485219478607 seconds
Average: 0.13485219 milliseconds per iteration
Peak CPU utilization: ~12%
Test 2: Initializing the generator in each loop
while ($i <= 1000) {
$zooIdGen = RobThree\HumanoID\HumanoIDs::zooIdGenerator();
$zooId = $zooIdGen->create($i);
echo $zooId . '<br>';
$i++;
}Result: Crashed after 615 iterations
Peak CPU utilazation: ~27%
Eventually finished with the following results
Result: 1000 loops took 22.121620178223 seconds
Average: 22.12162018 milliseconds per iteration
Test 3: Initializing the generator as a singleton in the service container
// In AppServiceProvider
$this->app->singleton('HumanoIDs', function ($app) {
return new HumanoIDs($app->make(HumanoIDs::class));
});
// Benchmark
while ($i <= 10000) {
$zooId = app('HumanoIDs')->generator->create($i);
echo $zooId . '<br>';
$i++;
}Result: 10000 loops took 22.320996999741 seconds
Average: 2.2320997 milliseconds per iteration
Peak CPU utilazation: ~21%
This actually suprised me as I thought the result between test 1 and 3 would be much closer. This makes me think that I need to bind the actual generator to the service container instead.
Test 4: Initializing the generator in the service container by binding the generator method
// In AppServiceProvider
$this->app->singleton('HumanoIDGenerator', function ($app) {
return new HumanoIDGenerator($app->make(HumanoIDGenerator::class));
});
// Intermediary class:
class HumanoIDGenerator
{
public \RobThree\HumanoID\HumanoID $generator;
public function __construct()
{
$this->generator = \RobThree\HumanoID\HumanoIDs::zooIdGenerator();
}
}
// Benchmark
while ($i <= 10000) {
$zooId = app('HumanoIDGenerator')->generator->create($i);
echo $zooId . '<br>';
$i++;
}Result: 10000 loops took 1.5630679130554 seconds
Average: 0.15630679 milliseconds per iteration
Peak CPU utilazation: ~12% for a short spike
This is just a tiny tiny bit slower than the first test, which is just what I initially expected.
Conclusion
When using Laravel, make sure to bind the actual generator to the service container and not just the main class.
