Using JMH to Benchmark Multi-Threaded Code
{UPDATE 03/09/14: If you come here looking for JMH related content start at the new and improved JMH Resources Page and branch out from there!} Exploring some of the multi-threading related functionality in JMH via a benchmark of false shared counters vs. uncontended counters. As discussed in previous post the JMH framework introduced by the good folk of the OpenJDK offers a wealth of out of the b

How to improve JPA performance by 1,825%
The Java Persistence API (JPA) provides a rich persistence architecture. JPA hides much of the low level dull-drum of database access, freeing the application developer from worrying about the database, and allowing them to concentrate on developing the application. However, this abstraction can lead to poor performance, if the application programmer does not consider how their implementation affe

» JNA vs P/Invoke from a performance perspective coUnity Software Development
Recently, I was asked to help evaluating whether Java (using JNA) or .NET/Mono (using P/Invoke) had the smaller performance overhead for accessing native code from a managed environment. The context The EPICS project is a joint research project of eight European research partnes in the field of sensor networks. The Pervasive Computing Group at the Alpen-Adria Universität Klagenfurt is participati
jna/www/DirectMapping.md at master · java-native-access/jna
JNA supports a direct mapping method which can improve performance substantially, approaching that of custom JNI. Method signatures are the same as they would be in a JNA interface mapping, but they can be any static or object methods. You only need register them within the static initializer of the defining class, as in the example below. The Native.register() method takes the name of your native
