Our code = Poor performance

@tobiasnyholm

Let’s talk about performance

@tobiasnyholm

Rule 1: Buy a better server

@tobiasnyholm

Rule 2: Use Varnish

@tobiasnyholm

Rule 3: Run less code

@tobiasnyholm

section .text global _start ; must be declared for linker (ld)

_start: ; tell linker entry point

mov edx,len ; message length mov ecx,msg ; message to write mov ebx,1 ; file descriptor (stdout) mov eax,4 ; system call number (sys_write) int 0x80 ; call kernel

mov eax,1 ; system call number (sys_exit) int 0x80 ; call kernel

section .data

Workflow component

<?php

use Symfony\Component\Workflow\DefinitionBuilder; use Symfony\Component\Workflow\Transition; use Symfony\Component\Workflow\Workflow; use Symfony\Component\Workflow\MarkingStore\SingleStateMarkingStore;

$definitionBuilder = new DefinitionBuilder(); $definition = $definitionBuilder->addPlaces(['draft', 'review', 'rejected', 'published']) ->addTransition(new Transition('to_review', 'draft', 'review')) ->addTransition(new Transition('publish', 'review', 'published')) ->addTransition(new Transition('reject', 'review', 'rejected')) ->build() ;

$marking = new SingleStateMarkingStore('currentState'); $workflow = new Workflow($definition, $marking);

$article = /* fetch from database */ if ($workflow->can($article, 'publish')) { $workflow->apply($article, 'publish');

// TODO redirect or any other action ... }

Cache component

namespace Symfony\Contracts\Cache;

/** * Gets/Stores items from/to a cache. * * On cache misses, a callback is called that should return the missing value. * This callback is given an ItemInterface object corresponding to the needed key, * that could be used e.g. for expiration control. */ interface CacheInterface { /** * @param callable(ItemInterface) $callback Should return the computed value for the given * key/item * @param float|null $beta A float that, as it grows, controls the likeliness * of triggering early expiration. 0 disables it, * INF forces immediate expiration. * * @return mixed The value corresponding to the provided key * * @throws InvalidArgumentException When $key is not valid or when $beta is negative */ public function get(string $key, callable $callback, float $beta = null); }

$result = $cache->get('foobar', function (ItemInterface $item) { $pi = null; /* Calculation of pi */ $item->expiresAfter(3600);

Middleware pattern

<?php

use Symfony\Component\HttpFoundation\Response; use Symfony\Component\HttpFoundation\Request; use App\Runner;

require __DIR__.'/../vendor/autoload.php';

$request = Request::createFromGlobals(); $response = new Response();

$middleware[] = function(Request $request, Response $response, callable $next) { if ($request->getMethod() !== 'GET') { return new Response('Method not allowed', 405); } return $next($request, $response); };

$middleware[] = function(Request $request, Response $response, callable $next) { $response->setContent('foobar'); return $next($response, $response); };

$runner = new Runner($middleware); $response = $runner($request, $response);

// Send response echo $response->getBody();

namespace App;

use Symfony\Component\HttpFoundation\Response; use Symfony\Component\HttpFoundation\Request;

class Runner { /** @var callable[] */ private $queue;

public function __construct(array $queue) { $this->queue = $queue; }

public function __invoke(Request $request, Response $response) { $middleware = array_shift($this->queue); if (null === $middleware) { // Default return function (Request $request, Response $response, callable $next) { return $response; }; }

return $middleware($request, $response, $this); } }

<?php

namespace App\Middleware;


interface MiddlewareInterface { public function __invoke(Request $request, Response $response, callable $next); }

namespace App\Middleware;


class Router implements MiddlewareInterface { public function __invoke(Request $request, Response $response, callable $next) { $uri = $request->getUri();

switch ($uri) { case '/': $response = (new \App\Controller\StartpageController())->run($request); break; case '/foo': $response = (new \App\Controller\FooController())->run($request); break; default: $response->setStatusCode(404); $response->setContent('Not Found'); break; }

return $next($request, $response); } }

<?php

use Symfony\Component\HttpFoundation\Response; use Symfony\Component\HttpFoundation\Request; use App\Runner;

require __DIR__.'/../vendor/autoload.php';

$request = Request::createFromGlobals(); $response = new Response();

$middleware[] = new Cache; $middleware[] = new NewRelic; $middleware[] = new Security; $middleware[] = new Router;

$runner = new Runner($middleware); $response = $runner($request, $response);

// Send response echo $response->getBody();

Custom kernel

use Symfony\Component\HttpFoundation\Response; use Symfony\Component\HttpFoundation\Request; use Symfony\Component\Config\Exception\FileLocatorFileNotFoundException; use Symfony\Component\Config\FileLocator; use Symfony\Component\DependencyInjection\Container; use Symfony\Component\DependencyInjection\ContainerBuilder; use Symfony\Component\DependencyInjection\Dumper\PhpDumper; use Symfony\Component\DependencyInjection\Loader\YamlFileLoader;

class Kernel { private $booted = false; private $debug; private $env;

/** @var Container */ private $container;

public function __construct(string $env, bool $debug = false) { $this->debug = $debug; $this->env = $env; }

/** * Handle a Request and turn it in to a response. */ public function handle(Request $request): Response { $this->boot();

require_once $containerDumpFile; $container = new \CachedContainer(); } else { $container = new ContainerBuilder(); $container->setParameter('kernel.project_dir', $this->getProjectDir()); $container->setParameter('kernel.environment', $this->env);

$container->registerForAutoconfiguration(EventSubscriberInterface::class) ->addTag('kernel.event_subscriber');

$container->registerForAutoconfiguration(Command::class) ->addTag('console.command');

$container->addCompilerPass(new AddConsoleCommandPass()); $container->addCompilerPass( new RegisterListenersPass(EventDispatcherInterface::class), PassConfig::TYPE_BEFORE_REMOVING );

$fileLocator = new FileLocator($this->getProjectDir().'/config'); $loader = new YamlFileLoader($container, $fileLocator); try { $loader->load('services.yaml'); $loader->load('services_'.$this->env.'.yaml'); } catch (FileLocatorFileNotFoundException $e) { }

$container->compile();

//dump the container @mkdir(dirname($containerDumpFile), 0777, true);

protected function configureRoutes(RouteCollectionBuilder $routes) { $confDir = $this->getProjectDir().'/config'; $routes->import($confDir.'/routes.yaml');

/** * A Kernel that provides configuration hooks. * * @author Ryan Weaver <[email protected]> * @author Fabien Potencier <[email protected]> */ trait MicroKernelTrait { abstract protected function configureRoutes(RouteCollectionBuilder $routes); abstract protected function configureContainer(ContainerBuilder $c, LoaderInterface $loader);

public function registerContainerConfiguration(LoaderInterface $loader) { $loader->load(function (ContainerBuilder $container) use ($loader) { $container->loadFromExtension('framework', array( 'router' => array( 'resource' => 'kernel::loadRoutes', 'type' => 'service', ), ));

if ($this instanceof EventSubscriberInterface) { $container->register('kernel', static::class) ->setSynthetic(true) ->setPublic(true) ->addTag('kernel.event_subscriber') ; }
