SymfonyCon returns to its roots! Join us in Warsaw (Poland) on November 26 and 27, 2026, for two days of world-class technical sessions. See more details here!
🎤 Speaker announcements
We are excited to introduce Mathias Arlaud, Software Engineer at baksla.sh ! He'll take the mic to present "Asynchronous PHP & Symfony in High-Performance Systems", taking a deep dive into runtime internals and architecture to help you engineer lightning-fast applications:
"Most Symfony applications buffer everything: Doctrine results, serialized objects, JSON, exports. They build the entire response, then send it. This works fine, until it doesn't: memory spikes, time-to-first-byte creeps up, and exports start dying in production.
LLMs make the problem impossible to ignore. When a model takes several seconds to answer, waiting for the return means staring at a spinner the whole time. Streaming isn't a back-end optimization anymore. It's the foundation modern user experience is built on.
In this talk, we tear down an assumption baked into most Symfony apps: that a response has to be fully built before it's sent. We'll rethink the data flow end to end, StreamedResponse, incremental JSON encoding with the JsonStreamer component, iterable Doctrine data sources, Server-Sent Events, and EventStreamResponse for real time.
You'll walk away knowing how to stream data as it's produced, power live interfaces, generate exports of several million rows, and keep memory flat, using tools already sitting in Symfony."
