Laravel 5 中注册多个 repository 的影响？

看到挺多项目中开始使用repository模式，然后会在serviceProvider中进行注册

如Flarum项目中CoreServiceProvider.php

public function register()
    {
        $this->app->bind(
            'Flarum\Core\Repositories\DiscussionRepositoryInterface',
            'Flarum\Core\Repositories\EloquentDiscussionRepository'
        );
        $this->app->bind(
            'Flarum\Core\Repositories\PostRepositoryInterface',
            'Flarum\Core\Repositories\EloquentPostRepository'
        );
        $this->app->bind(
            'Flarum\Core\Repositories\UserRepositoryInterface',
            'Flarum\Core\Repositories\EloquentUserRepository'
        );
        $this->app->bind(
            'Flarum\Core\Repositories\ActivityRepositoryInterface',
            'Flarum\Core\Repositories\EloquentActivityRepository'
        );
        $this->app->bind(
            'Flarum\Core\Repositories\NotificationRepositoryInterface',
            'Flarum\Core\Repositories\EloquentNotificationRepository'
        );
    }

这个时候才5个repository，但我们当项目大了之后一般都有好几百个repository，这样再进行注册，会不会页面打开特别慢呢，有没有什么更好的处理方法
