How HotSpot Sees Your Code
Just as a database creates an execution plan to run your SQL queries, HotSpot analyzes your Java code to determine how to best to run your code. And just as with a database where understanding indexes is important to achieving performance, there are a few core concepts that important to understanding Java performance.
In this talk, we'll explore the way HotSpot examines a piece of code in detail, learning not just about the optimizations that HotSpot performs but the hazards that get in its way. In the end, you'll learn how to work with HotSpot so you can write faster code with less effort.
