About Nitsan:
A blogger (http://psy-lob-saw.blogspot.com/) and a coder with a pedantic passion for performance. My work has spanned army intelligence systems, dot.com era startups, financial institutions and innovative product companies. Currently the Lead Performance Eng. for Azul Systems (http://www.azulsystems.com/) by day, and main contributor to kickass lock free data structures library JCTools (https://github.com/JCTools/JCTools) by night.

We will take a deep dive into the guts of Honest-Profiler, an unbiased sampling CPU profiler for the JVM, and the JVM internals which enable it to work.

• Introduction: CPU profiling, sampling and biases explained.

• How does it hang together? interrupts, non-blocking code and an unofficial API

• Sampling the instruction pointer: how it works and limits of accuracy

• Walking the stack: demangling a mixed Java/native stack, challenges and limitations

• Reading a profile: flat profile vs. tree profile vs. flamegraphs

The talk will include some counter examples from other profilers(JVisualVM/JMC/YourKit/ZVision).
