Maximizing Applications Performance with GraalVM

GraalVM is a high-performance virtual machine offering new optimizations for individual languages and seamless interoperability for polyglot applications. One of the interesting features one can get with GraalVM is the freedom to choose between JIT and AOT compilation modes. This way you can optimize for different performance metrics, employing proper developer tools, and selecting the best language libraries for the job.  

In this session, we'll go through optimization strategies for the most common cases, discuss benefits and trade-offs of each case, and discuss what the latest project updates, such as Java 11 support and the GraalVM 20.0 major release, can offer for speeding up your applications. We'll also take a look at how to make real-world applications GraalVM-ready, and how languages like JavaScript, Ruby, R and Python can also benefit from GraalVM.

Understanding CPU Microarchitecture to Increase Performance

Microprocessors have evolved over decades to eke out performance from existing code. But the microarchitecture of the CPU leaks into the assumptions of a flat memory model, with the result that equivalent code can run significantly faster by working with, rather than fighting against, the...

Performance vs. New Features: It Doesn’t Have to Be a Zero-Sum Game

In this talk we'll explore implementing CRC checksums for a durable log while trying to retain respectable performance. We'll discuss motivations for applying checksums and explore how convoluted this process can be. We need to deal with missing/convoluted APIs to get the basics working....
