Is it still C#? Pushing .NET to its Absolute Limits at WeAreDevelopers World Congress 2026 | RavenDB
Ever wondered what happens when you push the .NET runtime to its physical limits? In this session live from WeAreDevelopers World Congress 2026 in Berlin, Szymon Kulec (Lead Developer Advocate at RavenDB and performance engineer) breaks down the hard-won engineering lessons behind building a high-performance, battle-tested database entirely in .NET. Whether you're crafting high-throughput microservices, wrestling with memory allocations, or trying to shave milliseconds off your hot paths, this talk is your blueprint for writing blazingly fast .NET code.💡 What You’ll Learn in This Deep Dive: JSON and Beyond: How RavenDB bypasses standard serialization overhead for zero-allocation efficiency. The Memory Game: Unlocking advanced allocation tricks, custom buffers, and memory management. Taming the State Machine: Eliminating unseen async/await overhead in performance-critical code paths. Beyond the Cache Line: Structuring data for peak CPU cache locality and SIMD execution. Vectorize Everything: Using hardware intrinsics to process data at hardware speeds. 🛠️ Surviving the Ecosystem: Practical systems-programming lessons you can apply directly to your everyday C# projects. ⏰ Timestamps: 00:00 – Intro: Pushing .NET Runtime to the Max 02:15 – JSON & Beyond: Blittable Data Formats 06:40 – The Memory Game & Avoiding Allocations 12:10 – Taming the Async/Await State Machine 18:35 – Cache Lines & Hardware Alignment 25:00 – Vectorization: SIMD in Practical C# 31:20 – War Stories from RavenDB Engineering 38:45 – Q&A & Key Takeaways for Everyday .NET Devs -- About RavenDB RavenDB is a multi-model NoSQL document database trusted by thousands of companies worldwide, built for teams that need to move fast without sacrificing stability.
