Hire php developer

Building a website and getting it to the highest performance level is not as easy as we may think of. Undoubtedly, PHP offers you a best-in-class range of frameworks that are developed to serve different aspects of online retail needs.

Talking about Symfony, it is a popular open-source framework of PHP that allows you to develop web applications, APIs, and other web services, etc. worldwide. Even though Symfony is being criticized by others to be the slowest one amongst other PHP frameworks.

Still, whenever you hire a PHP developer to build an application, you can ask them to incorporate the below-mentioned performance optimization tips from day one that will help you leverage the best of your Symfony framework.

Let’s start!

Stick to the latest version!

Choosing the latest version of any sort of software is recommended due to several reasons. First, you would get new features incorporated. Second, security improvements would be present there. Last, it would contribute to your website’s overall performance.

If you are an existing Symfony user, you should upgrade the version with the latest and superior one. Though it would consume time and energy while delivering new functionality, the performance you would get is worth it. However, it is important to keep a backup of your older website.

Additively, get an in-built Caching.

A cache is a copy of your HTML pages or images that a web server stores to present it to visitors for their next time arrival. Any invalid or unnecessary cache may result in the slow performance of your website. It does not only help you to enhance UX but also increase the website performance by reducing page download times.

The benefits of sticking to the latest versions of PHP also cover this benefit of the cache. With PHP 7.x, you would get an in-built extension called OPcache that provides in-memory storage of precompiled bytecode of your website while cutting down on several parse scripts every time they are used. While using Symfony, OPcache reflects the best practices to enhance performance.

Do some composer autoload optimization!

Just like Laravel, Symfony would be registering different autoloaders by default. In this manner, it offers assistance to load classes and aliases for your web application. Symfony also utilizes the composer to determine the way of classes autoload within an application.

You can either use composer dumpautoload or composer dump-autoload to optimize this composer autoload in Symfony.

Efficient data retrieval

To perform this performance optimization trick, you need to identify slow queries in your Symfony application through a slow query log on the layers of the database. However, try to perform this in a test environment, as it may cause some additional performance issues if performed on a live application.

Skip ORM in Symfony

Symfony software genre is ORM, i.e., object-relational mapping. Built to map your database to objects, it often makes things easy in development, but you need to skip it for enhanced performance. Skipping ORM in our Symfony application may seem adversary.

However, the mapping of large objects along with their associates can cause issues like deserializing, or hydrating which can, further, slow down your Symfony application. To avoid these issues, you can choose to demolish the ORM layer altogether.


Although you can build websites with PHP itself, still choosing a framework would help you to cut down on development costs along with the increased efficiency of the final product. When we talk about performance benchmarking, PHP has faced several critics. Fortunately, it has always succeeded to improve with every version update.

However, you can always look up to some best performance optimization techniques, as mentioned in this post. At last, I hope that all tips that are discussed above would help you to tune-in Symfony powered app’s performance.
