Open Source Summit + Embedded Linux Conference North America 2026

The classic Java mantra, "write once, run anywhere," suggested that developers should be able to rely on the JVM to handle the intricacies of different hardware environments. For all modern high level languages, we expect compilers and language runtimes to “abstract away” the hardware for application developers. However, the hardware can still impact application performance. Developers and architects should know enough about the behavior of the underlying hardware to avoid pitfalls and take advantage of opportunities to maximize performance.


In this talk, you will learn about:

- How modern CPU pipelining and memory models can impact application performance
- How to think about data locality and memory access patterns when choosing algorithms for your applications
- Some Arm64 features you can leverage to improve performance

This session is ideal for software developers who want to understand how server architecture influences application performance, and how to make informed decisions about the underlying architecture when deploying applications to the cloud.
