Psychosomatic, Lobotomy, Saw: Talks
http://psy-lob-saw.blogspot.com/p/talks.html
Psychosomatic, Lobotomy, Saw. It's X, you'll need Y, I'll get Z. I've talked in some conferences/LJC meetings and some people seem to have enjoyed the talks. I'm not a great public speaker (improving over time, I think), and personally I would rather read an article/book/post than see a video on the same topic. But some people have enjoyed the talks, and some conference organizers have asked me to come back, so what do I know. GeekOut, Tallin 2015. SkillsMatter, London 2014. GeeCon, Krakow 2014. JVM Prof...
Psychosomatic, Lobotomy, Saw: HdrHistogram: A better latency capture method

Psychosomatic, Lobotomy, Saw. It's X, you'll need Y, I'll get Z. Monday, 16 February 2015. HdrHistogram: A better latency capture method. The above data structure was an easy solution to a problem we had little time to solve, but it left much to be desired. These days the histogram problem is gloriously solved by the HdrHistogram. High Dynamic Range), and though it's been around for a couple of years now I still find olden hand rolled histograms in many a code base. Cut that shit out boys and girls!

Psychosomatic, Lobotomy, Saw: Diving Deeper into Cache Coherency
http://psy-lob-saw.blogspot.com/2013/09/diving-deeper-into-cache-coherency.html
Psychosomatic, Lobotomy, Saw. It's X, you'll need Y, I'll get Z. Sunday, 15 September 2013. Diving Deeper into Cache Coherency. I recently gave a talk about Mechnical Sympathy at Facebook, which was mostly a look at the topic through the SPSC queue optimization series of posts. During the talk I presented the optimisation step (taken in Martin's original series of queue implementations) of adding a cache field for the head and tail. Moving from this. Not what I stated previously here. I say mostly and no...

http://psy-lob-saw.blogspot.com/p/jmh-related-posts.html
Psychosomatic, Lobotomy, Saw. It's X, you'll need Y, I'll get Z. I've been an early adopter of JMH and written a fair few posts which either drill into a particular aspect of JMH or demonstrate it's usage in a given context. In this page I plan to maintain a high level view of what's where. Is a Java Micro-benchmarking Harness written by the Oracle/Sun Performance Engineering team (with Shipilev. The framework consists of a few main groups of functionality:. Reporting formats - JSON, CSV, Summary. Asymme...

Ideas Not For Sale. Nothing is more dangerous than an idea when it is the only one you have. (Emile Chartier). Why clone is faster than constructor copy. This post is a followup on my previous post. About copying objects in Java. After I published that post I got a question from Sven Reimers (@SvenNB) why there is a big performance different between clone and copying via constructor. In this post I will try to answer this question. Just to recap what we are looking at. There are 2 classes implementing.

Ideas Not For Sale. Nothing is more dangerous than an idea when it is the only one you have. (Emile Chartier). Copy object in Java (performance comparison). This blog came about because I was looking into performance issue and profiling showed that a method that was copying objects was very slow. (. The fact that this method was called millions of times was an actual bug not the slowness of the copy routine. The method to copy object was performing field by field copy using. Returns a copy of the. Method...

Java 8 Concurrency: LongAdder | mind.out

A software engineer's brain dump. Laquo; JS1K Tips: Writing Tiny JavaScript. Java 8 Concurrency: LongAdder. 11 May, 2013. What began as a small peek at JDK source code quickly showed me a whole new side of Java. I found that yes, LongAdder is faster (see graph on the right). And I also learned a bit about how atomics are implemented in Java. It turned out to be more complex and more interesting than I expected. First, how well does LongAdder perform? I downloaded the latest preview of JDK 8. All threads ...
