If you care about Java performance and the future of the JVM, Cay Horstmann’s talk on Project Valhalla is absolutely worth your time.
Here’s why you should watch it 👇
✨ Valhalla in one sentence
It brings value types to Java – “code like a class, act like an int” – with less heap allocation, better memory layout, and lower GC pressure.
🎯 What you’ll get from the talk
🚀 A clear, practical explanation of what value types really are
🧱 How Valhalla flattens objects in memory for huge performance wins
🧪 A hands‑on tour of tools to see Valhalla at work:
- JMH (microbenchmarks)
- Java Flight Recorder & Mission Control (allocations & GC)
- JITWatch (JIT optimizations)
- JOL – Java Object Layout (real memory layout)
💡 Why it’s worth watching
- You’ll finally understand how Valhalla can speed up real-world code (math-heavy logic, dense collections, IDs, domain value objects).
- You’ll learn concrete techniques to benchmark and analyze your own Java workloads today, so you’re ready when Valhalla lands.
- It’s not hand‑wavy theory: it’s grounded in measurements, tools, and JVM internals explained in accessible language.
If you’re a Java dev who likes to know where the platform is heading (and how to squeeze more out of it) put this talk on your watch list.
