求解释 Laravel 的服务与中间件？

laravel的性能优化命令：

php artisan config:cache
php artisan route:cache
php artisan optimize

除了上面优化命令之外，我还想注释掉业务用不到的中间件和服务。

\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class
\App\Http\Middleware\EncryptCookies::class
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class
\Illuminate\Session\Middleware\StartSession::class
\Illuminate\View\Middleware\ShareErrorsFromSession::class
\App\Http\Middleware\VerifyCsrfToken::class
\App\Http\Middleware\Authenticate::class
\Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class
\App\Http\Middleware\RedirectIfAuthenticated::class
Illuminate\Foundation\Providers\ArtisanServiceProvider::class
Illuminate\Auth\AuthServiceProvider::class
Illuminate\Broadcasting\BroadcastServiceProvider::class
Illuminate\Bus\BusServiceProvider::class
Illuminate\Cache\CacheServiceProvider::class
Illuminate\Foundation\Providers\ConsoleSupportServiceProvider::class
Illuminate\Routing\ControllerServiceProvider::class
Illuminate\Cookie\CookieServiceProvider::class
Illuminate\Database\DatabaseServiceProvider::class
Illuminate\Encryption\EncryptionServiceProvider::class
Illuminate\Filesystem\FilesystemServiceProvider::class
Illuminate\Foundation\Providers\FoundationServiceProvider::class
Illuminate\Hashing\HashServiceProvider::class
Illuminate\Mail\MailServiceProvider::class
Illuminate\Pagination\PaginationServiceProvider::class
Illuminate\Pipeline\PipelineServiceProvider::class
Illuminate\Queue\QueueServiceProvider::class
Illuminate\Redis\RedisServiceProvider::class
Illuminate\Auth\Passwords\PasswordResetServiceProvider::class
Illuminate\Session\SessionServiceProvider::class
Illuminate\Translation\TranslationServiceProvider::class
Illuminate\Validation\ValidationServiceProvider::class
Illuminate\View\ViewServiceProvider::class
App\Providers\AppServiceProvider::class
App\Providers\AuthServiceProvider::class
App\Providers\EventServiceProvider::class
App\Providers\RouteServiceProvider::class

要想注释掉上面的一些中间件和服务，那就必须了解它们的大致作用。
我对laravel了解不是很深刻，所以发了这帖子，请各位帮帮忙，给每个中间件与服务做个注释，拜谢啦。
