PRÉSENTATION GÉNÉRALE

Nous présentons aujourd'hui un petit retour d'expérience sur le composent Symfony Messenger. L'objectif derrière ce billet est de comprendre comment:

1. Mettre en place une architecture de conteneur Docker qui répond à notre besoin.
2. Fonctionnement de l'ordonnancement avec RabbitMq.
3. Fonctionnement de Symfony Messenger.
4. Le couplage de Symfony Messenger et RabbitMQ, SQS, Redis...afin d'envoyer des emails d'une façon asynchrone.

De nombreux de traitement web pourrait être assez lourd qui prennent parfois beaucoup de temps soit à cause d'un trafic intense,soit à cause d'une mauvaise architecture logicielle, soit à cause de la mauvaise gestion de mémoire, y a des gens qui préfèrent augmenter la mémoire ou bien mettre un système de balance loader ...Mais ca résout pas le problème principal.

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
