I'm not going to tell you to rebuild your application in Rust. At all. I love Symfony (and PHP), we all do. But there are times when we hit a performance roadblock. Or run out of memory. Maybe even both.

In this talk, we’ll replace part of our logic with a native helper using PHP’s FFI and Rust. We’ll explore performance gains, show practical implementation steps, and discuss when native code makes sense. And finally, I’ll share a skeleton project so you can start experimenting in tonight.
