<p>你們都知道 laravel 項目寫起來是挺爽，可是在生產環境性能不高，咱們來抽絲剝繭分析我本身項目的運行時間消耗：</p> <h2>Bootstrap 耗時</h2> <table> <thead><tr> <th>步驟</th> <th>耗時</th> </tr></thead> <tbody> <tr> <td><code>Illuminate\Foundation\Bootstrap\LoadEnvironmentVariables</code></td> <td>0.3058910369873</td> </tr> <tr> <td><code>Illuminate\Foundation\Bootstrap\LoadConfiguration</code></td> <td>3.6571025848389</td> </tr> <tr> <td><code>Illuminate\Foundation\Bootstrap\HandleExceptions</code></td> <td>0.78296661376953</td> </tr> <tr> <td><code>Illuminate\Foundation\Bootstrap\RegisterFacades</code></td> <td>9.0579986572266</td> </tr> <tr> <td><code>Illuminate\Foundation\Bootstrap\RegisterProviders</code></td> <td>101.02701187134</td> </tr> <tr> <td><code>Illuminate\Foundation\Bootstrap\BootProviders</code></td> <td>96.982002258301</td> </tr> </tbody> </table> <p>觀察初步結論： laravel 在調用 <code>Illuminate\Foundation\Bootstrap\RegisterProviders</code> 和 <code>Illuminate\Foundation\Bootstrap\BootProviders</code> 的 <code>bootstrap</code> 方法時，消耗時間是大頭。</p> <ul> <li>類 <code>Illuminate\Foundation\Bootstrap\RegisterProviders</code> 是用於註冊服務提供者的。</li> <li>類 <code>Illuminate\Foundation\Bootstrap\BootProviders</code> 是用於啓動服務提供者的。</li> <li>laravel 的內置server <code>php artisan serve</code> 自帶了優化機制，上面數據僅體現首次加載的耗時。二次加載時會相比少不少。但此優化在 fpm 下無效。</li> </ul> <p>咱們進一步分析。</p> <hr> <h3>RegisterProviders 耗時</h3> <p><code>\Illuminate\Foundation\Bootstrap\RegisterProviders::bootstrap</code> 方法代碼以下：</p>php
/**
* Bootstrap the given application.
*
* @param \Illuminate\Foundation\Application $app
* @return void
*/
public function bootstrap(Application $app)
{
$app->registerConfiguredProviders();
}
<p>因此咱們仍是回到了 <code>\Illuminate\Foundation\Application</code> 這個文件：</p>laravel
/**
* Register all of the configured providers.

public function registerConfiguredProviders()
{
$providers = Collection::make($this->config['app.providers'])
->partition(function ($provider) {

});
$providers->splice(1, 0, [$this->make(PackageManifest::class)->providers()]);
(new ProviderRepository($this, new Filesystem, $this->getCachedServicesPath()))
->load($providers->collapse()->toArray());
}
<p>針對上面的 <code>(new ProviderRepository)->load</code> 進行耗時分析發現數據爲</p> <table> <thead><tr> <th>步驟</th> <th>耗時</th> </tr></thead> <tbody><tr> <td><code>Illuminate\Foundation\ProviderRepository::load</code></td> <td>61.771869659424</td> </tr></tbody> </table> <p>毋庸置疑這就是消耗時間的大頭。 </p> <p>裏面的代碼爲</p>git
/**

*/
public function load(array $providers)
{
$manifest = $this->loadManifest();
// First we will load the service manifest, which contains information on all
// service providers registered with the application and which services it

if ($this->shouldRecompile($manifest, $providers)) {
$manifest = $this->compileManifest($providers);

// Next, we will register events to load the providers for each of the events
// that it has requested. This allows the service provider to defer itself

foreach ($manifest['when'] as $provider => $events) {
$this->registerLoadEvents($provider, $events);

// We will go ahead and register all of the eagerly loaded providers with the

foreach ($manifest['eager'] as $provider) {

$this->app->addDeferredServices($manifest['deferred']);
}
<p>而再通過定位，發現慢在這一行</p>github
foreach ($manifest['eager'] as $provider) {
$this->app->register($provider);
}
<p>又回到 <code>\Illuminate\Foundation\Application</code></p>web

if (method_exists($provider, 'register')) {
