Quarkus makes both people and hardware more efficient. That’s cool, but how does it work? Usually, we expect to trade-off developer experience against runtime efficiency. In this session, Holly will dive into some of the technical underpinnings of Quarkus’s efficiency. She’ll give advice for those using or considering Quarkus - should you be doing reactive programming? Do native binaries run fastest? In this under-the-hood session, she’ll also share general principles and transferrable discoveries from the engineering team, such as knowing what you’re optimising for, avoiding cache pollution, and how to be static-but-dynamic.
