Benchmarks: Laravel

How fast is Laravel compared to other PHP frameworks? Benchmark results in requests-per-second (check methodology section to understand how they were conducted) prove it to be times slower than all others:

Framework test/html Faster test/json Faster
Lucinda + 48.49 X + 52.16 X
Symfony + 10.67 X + 11.88 X
CodeIgniter + 7.11 X + 7.25 X
Laravel    

Why is it so unbelievably sluggish, over 10 times slower than its main competitor (Symfony)? The main culprit is over-programming and loads of logic inside that should only ran when required (as improvements by tweaks below demonstrate).

Tweak #1

One of the things that contributes to slowness is the fact that on every request, framework opens a session and saves a new file. This questionable decision makes framework twice slower but it can be easily corrected in app/http/Kernel.php by commenting following lines:

protected $middlewareGroups = [ 'web' => [ \App\Http\Middleware\EncryptCookies::class, \Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class, // \Illuminate\Session\Middleware\StartSession::class, // \Illuminate\Session\Middleware\AuthenticateSession::class, // \Illuminate\View\Middleware\ShareErrorsFromSession::class, // \App\Http\Middleware\VerifyCsrfToken::class, \Illuminate\Routing\Middleware\SubstituteBindings::class, ], ];

Once that is done, framework becomes twice faster, but still in desperate need of more tweaks. Results in requests per second:

Framework HTML Rendering JSON Rendering
Laravel (tweak #1)
Laravel (factory settings)

Tweak #2

Let us tweak laravel to the max and keep only services strictly required in MVC. This means emptying all middleware in app/http/Kernel.php so it becomes:

namespace App\Http; use Illuminate\Foundation\Http\Kernel as HttpKernel; class Kernel extends HttpKernel { protected $middleware = []; protected $middlewareGroups = [ 'web' => [], 'api' => [], ]; protected $routeMiddleware = []; }

then modifying $providers and $aliases in config/app.php to become:

'providers' => [ Illuminate\Encryption\EncryptionServiceProvider::class, Illuminate\Filesystem\FilesystemServiceProvider::class, Illuminate\Queue\QueueServiceProvider::class, Illuminate\View\ViewServiceProvider::class, App\Providers\RouteServiceProvider::class, ], 'aliases' => [],

Even with such drastic (unrealistic) changes, results only improve marginally:

Framework HTML Rendering JSON Rendering
Laravel (tweak #2)
Laravel (tweak #1)
Laravel (factory settings)

General Conclusion

Trying to optimize Laravel for performance is a job destined for failure. It seems its developers had zero performance concerns on their product: loads of logic is bundled for no reason and framework itself is massively over-programmed. All of these make Laravel incompatible with performance, so caching or related solutions will be your only viable options.
