Grant Jenks - Python Sorted Collections - PyCon 2016: https://youtu.be/7z2Ki44Vs4E?t=16m18s

(yes, it's python but could be adopted to Java and I wager it would have a better performance than the RBTree / AVLTree / etc implemetnations since it uses contiguous memory locations - AKA arrays :-))

Benchmarking the cost of primitive operations on the JVM

+Nitsan Wakart btw, I too was worried that the "blackhole" mechanism would dominate the measurement, but since the results are very close to what I expected (minus some surprises which I mentioned) I think that the calibration JMH performs works pretty well to eliminate the overhead.

I'm trying to put together a "how to get started in the JVM performance tuning field" presentation for the local JUG. Any feedback is very welcome:

(I realize that this is probably better as a one week workshop, but I'm trying to point people towards a couple of starting points and hope that they figure it out for themselves)

"Intel Software Guard Extensions (SGX) by Victor Costan and Srinivas Devada (NSF)"

Besides discussing SGX, it also contains a great overview of modern hardware, well worth the read for every developer!

Two years ago I painfully researched and built JMM Pragmatics talk and transcript, hoping it would highlight the particular dark corners of the Java Memory Models for those who cannot afford to spend years studying the formalisms, and deriving the actionable insights from them.

Boss: We won a contract to write software for voting machines. Dilbert: Who do you want to be president? Boss: Why do you ask? Dilbert: Because I want you to be happy. Boss: You're implying that you plan to fudge the system. Dilbert: I'm not implying anything like that. Obviously, it will be easy to fudge the data, and we are far happier when you're in a good mood.
