Join us for the second Performance Engineering Meetup where we'll discuss all things related to optimizing software performance!
Agenda
👨🏫 18:00 – Honey, I shrunk the data center by Przemysław Lalak (Allegro)
Ever wondered what happens if you actually pull the plug on an entire data center? Not just reroute traffic, but a full physical shutdown? Well, that's exactly what we've been doing for the past five years. In this talk, I want to share our journey and what we’ve learned from these pretty intense chaos experiments.
👨🏫 19:00 – A Journey of Improvement: Evolving from Ad Hoc to a Robust Performance Testing Process by Tomasz Popiołek & Jakub Zamojski (CircleK)
This presentation outlines our journey from ad-hoc, late-stage performance testing to a structured, proactive approach. Working in an agile, cloud-based environment, we improved by shifting testing earlier, choosing the right tools, and building a stable open-source platform. The adoption of Gatling Enterprise and team training helped strengthen our performance culture.
👨🏫 20:00 – Networking
After each session, there will be a Q&A where you can dive deeper into the topics and get your questions answered. And of course, no meetup is complete without pizza 🍕 and refreshing non-alcoholic craft beers 🍺

About the Performance Engineering Community
We are a community-driven initiative powered by Sabre, SII, Cytiva, Pega, IG Group, Circle K and Allegro. Our mission? Bringing engineers together to share knowledge, exchange experiences, and connect. But it’s not just about tech—it’s about people too. That’s why we make sure our meetups have a great vibe, with plenty of opportunities to chat, network, and just have a good time!
