Phalcon is the fastest PHP framework, followed by Laminas and Slim. Phalcon compiles in C extensions, with the highest performance; Laminas enables lightweight and flexibility by loading components on demand; Slim is suitable for building small APIs and services; while Laravel is not the fastest, its rich functionality and ease of use make it efficient and practical enough in most projects.

When it comes to speed, PHP frameworks vary a lot depending on what you're building and how you use them. If you want raw performance with minimal overhead, Laminas (formerly Zend Framework) and Phalcon stand out — especially Phalcon, which is built as a C extension and runs super fast. But speed isn't everything — simplicity, ease of use, and development efficiency also matter.

Lightweight and Fast: Laminas and Phalcon

If you're chasing pure performance, Laminas and Phalcon are your best bets. Laminas is known for being flexible and powerful while still keeping things pretty lean if you use only the components you need. It's not a full-stack framework by default, so you can pick and choose what to include, which helps keep things fast.

Phalcon , on the other hand, is unique because it's compiled as a PHP extension written in C. That means it runs directly inside the PHP kernel without needing extra layers or interpretation at runtime. This makes it incredibly fast out of the box. You don't get as much built-in scaffolding as Laravel, but that's part of why it's so quick.

• Laminas: modular, reusable components
• Phalcon: compiled, low memory usage, high performance

Both are great choices when speed is critical, but Phalcon edges ahead in benchmarks.

Laravel Isn't the Fastest, But Still Good Enough for Most Projects

Let's be honest — Laravel isn't the fastest PHP framework around. It has a lot of features, abstractions, and layers that make development easier but add some overhead. However, for most real-world applications, the difference in speed between Laravel and something like Phalcon is negligible unless you're handling millions of requests per day.

That said, Laravel makes up for it with developer happiness, clean syntax, and a huge ecosystem. If you're building something where development speed matters more than microsecond-level performance, Laravel is still a solid choice.

• Easier to learn and use than Phalcon
• Built-in tools for auth, routing, ORM, queues, etc.
• Performance can be improved with caching and tuning

So while Laravel might not win any speed contests, it's still plenty fast for most use cases — especially when paired with tools like Redis or OPcache.

Micro-Frameworks Like Slim Are Great for APIs and Small Apps

If you're building something lightweight like a REST API or a small service, a micro-framework like Slim could be perfect. These frameworks strip away almost all overhead and give you just the essentials: routing, middleware, and maybe dependency injection.

They're not mean for large apps with lots of business logic, but they shine in scenarios where you want to process HTTP requests quickly and efficiently.

• Very low overhead
• Easy to set up for simple endpoints
• Good for JSON APIs or microservices

Slim, in particular, is well-documented and actively maintained. If your app doesn't need database migrations, queue workers, or complex routing, this is a great option.

Speed ??matters, but it's not the only factor. For most developers, choosing the right tool depends on the project type, team familiarity, and long-term maintenance. If you really care about performance, go with Phalcon. If you want balance and productivity, Laravel still works well. And for tiny services or APIs, Slim or similar micro-frameworks are hard to beat.

Basically that's it.
