High Performance Networking on the JVM - Lessons learned
This presentation was hold as part of JAX 2013 in Mainz
Invoke Interface Optimisations
I'm often asked about the performance differences between Java, C, and C++, and which is better. As with most things in life there is no black and white answer. A lot is often discussed about how managed runtime based languages offer less performance than their statically compiled compatriots. There are however a few tricks available to managed runtimes that can provide optimisation opportuniti
Memory Access Patterns Are Important
In high-performance computing it is often said that the cost of a cache-miss is the largest performance penalty for an algorithm. For many years the increase in speed of our processors has greatly outstripped latency gains to main-memory. Bandwidth to main-memory has greatly increased via wider, and multi-channel, buses however the latency has not significantly reduced. To hide this latency our

Garbage Collector Performance Issues | Confluence Data Center 8.9 | Atlassian Documentation
Still need help? The Atlassian Community is here for you. Ask the community The information on this page relates to memory management with Oracle's Hotspot JVM. These recommendations are based on our support team's successful experiences with customers with large Confluence instances. Which garbage collector?Confluence uses the garbage first garbage collector (G1GC) by default. This is the garbage
PerformanceTechniques - HotSpot Internals for OpenJDK - wikis.sun.com
Performance techniques used in the Hotspot JVM What code shapes does the JVM optimize best? Here is a list. Knowing these optimizations may help language implementors generate bytecodes that run faster. Basic information about bytecodes is in Chapter 7 of the JVM Spec.. In the context of this discussion, "compiler" = "JIT", and usually more specifically refers to the server (or final tier) JIT. Ge

JVM Performance Tuning
Last week was JBoss World, and it was exciting to be a part of it. I gave a presentation on performance tuning our Enterprise Application Platform or EAP, and it was packed. In fact, people were sitting on the floor in pretty much all available space. What struck me about the presentation, and much of the discussion I had with individuals afterwards, is that JVM tuning is a big topic. So, I though
