Symfony's Performance Secret

Symfony’s Developer Experience ➔ Symfony is easy and pleasant to use ➔ It relies a lot on: ● conventions: automatic service registration, autowiring, autoconfiguration… ● User-friendly formats: attributes, YAML/PHP/XML config, Twig templates…

No content

The Cost of Developer Experience ➔ Parsing ➔ Compiling ➔ Dumping ➔ Using the reflection API ➔ … ➔ Many computations ➔ Potentially low

Alleviate The Cost ➔ Config: config files (YAML, XML…) are parsed, combined, converted in PHP and dumped ➔ DependencyInjection: the container is compiled and dumped for performance in production (uses Config under the hood) ➔ Routing (uses Config under the hood) ➔ Twig: templates are compiled in PHP files ➔ Cache: result of computations can be stored in cache

The var/cache directory

⚡ in Production: Symfony Apps Are Compiled ➔ The cache is populated 1 time, ideally at build time ● bin/console cache:warmup ➔ Then it is reused for each request

🐢 in Dev ➔ Each time a file (PHP, Twig, YAML…) is touched… ➔ … the cache must be re-populated ➔ Populating the cache means writing files on disk (slow) ➔ On large projects (ex: Sylius), this can be very slow and hurts the DX

Rebuild Only What’s Needed

The Easiest Way For Symfony Users

FrankenPHP’s Worker Mode

FrankenPHP Superpower: The Worker Mode ➔ Boot your application once ➔ Keep it in memory ➔ Process incoming requests without having to boot your app again ➔ Relies on goroutines and channels ➔ Somewhat similar to RoadRunner ➔ Unlike RoadRunner ● runs in process: no network calls, no gRPC ● uses plain old superglobals: no PSR-7

The Runtime Component

FrankenPHP worker for Symfony # Install $ composer require \ php-runtime/frankenphp-symfony # Run $ frankenphp \ -r public/ -w public/index.php

Benchmarks

Worker mode: Benchmark (Laravel Octane) 🧪 # Concurrency 1 for 5 seconds… ./vendor/bin/pest stress http://127.0.0.1:8000 Swoole Medium Request Duration ........... 4.94 ms RoadRunner Medium Request Duration ....... 2.61 ms FrankenPHP Medium Request Duration ....... 0.88 ms # Concurrency 8 for 5 seconds… ./vendor/bin/pest stress http://127.0.0.1:8000 --concurrency=8 Swoole Medium Request Duration ........... 5.39 ms RoadRunner Medium Request Duration ....... 4.00 ms FrankenPHP Medium Request Duration ....... 1.59 ms Benchmark by Nuno Maduro (Laravel Core Team) using Pest’s stress testing plugin on a M1 pro.

FrankenPHP In Dev?

We Have A Problem ➔ Worker scripts are started at the same time as the web server ➔ They run forever ➔ If a file change (PHP file, Twig template, config…) ● nothing happens ● the worker script keeps running ➔ Worker mode is useless in dev

New In FrankenPHP 1.4: Watchers frankenphp { worker { file ./public/worker.php watch } }

Watchers ➔ FrankenPHP will watch files or directory for changes ➔ When a watcher file changes, the worker script is automatically restarted ➔ By default, typical Symfony files are watched: ● PHP ● YAML ● Twig ● .env

Patterns Can Be Customized frankenphp { worker { file public/index.php watch /path/to/app watch /path/to/app/*.php watch /path/to/app/**/*.php watch /path/to/app/**/*.{php,twig} } }

Watchers Are Blazing Fast, even for thousands of files

Worker In Dev Is Useful ➔ To render most web pages, browsers send several HTTP requests in parallel ➔ If these requests are handled by PHP (ex: JS, Turbo, React…), you’ll benefit from worker mode even in dev: the app will be hot

FrankenPHP And Symfony Cache?

Watchers And Symfony Cache Using the worker mode has another benefit: ➔ Symfony cache is refreshed instantly, in the background, when you save a file in your editor ➔ This dramatically reduces the time before the page is available ➔ Before: save ➡ refresh ➡ cache is building… ➔ After: save ➡ cache is building… ➡ refresh
