Douglas Hawkins
Gateway Software Symposium
St. Louis · April 15 - 16, 2016
Lead Developer Java Performance Monitoring at Datadog
Douglas Hawkins has been passionately developing software for the past 20 years.
Throughout Doug's career, he has focused on creating performance intensive applications
in Java ranging from bioinformatics to financial exchanges.
After 10 years as a Java developer, Doug transitioned to working on Azul's Java Virtual Machine.
Today, Doug continues his interest in building performance tools for developers working on Datadog's Java Application Performance Monitoring.
While Doug's passion for developing software remains, his true passion is in sharing his
interest in low-level details and JVM performance with others.
Presentations
Java Optimizations That Matter (and Some That Don't)
Early releases of Java performed poorly, but those issues largely disappeared long ago with the introduction of HotSpot. However, much of the performance advice for Java persists through hearsay from those early days.
How (Not) To Measure and Profile Java Performance
Today, we all benefit from the sophistication of modern compilers and hardware, but that extra complexity can also make it difficult to reason about performance.
Concurrency Concepts in Java
Unlike other languages, Java had a well-defined memory model from the very beginning, but over the years additional packages and low-level features have been added to make the most of today's hardware.
In this talk, we'll discuss concurrency in detail starting at the hardware up to Java's latest synchronization mechanisms and finally onto high-level concurrent collections.
