Zulu – Certified OpenJDK 8 builds for all operating systems


You might have heard that Java is Open Source. And then you noticed that the Java SE downloads from the Oracle website are not actually Open Source. Maybe you also heard about OpenJDK. So how does this fit together? OpenJDK is an Open Source implementation of Java and Oracle Java engineers do work on Java […]

Java Best Practices – High performance Serialization


via Java Best Practices – High performance Serialization | Java Code Geeks.

Continuing our series of articles concerning proposed practices while working with the Java programming language, we are going to discuss and demonstrate how to utilize Object Serialization for high performance applications.

All discussed topics are based on use cases derived from the development of mission critical, ultra high performance production systems for the telecommunication industry.

Prior reading each section of this article it is highly recommended that you consult the relevant Java API documentation for detailed information and code samples.

All tests are performed against a Sony Vaio with the following characteristics :

  • System : openSUSE 11.1 (x86_64)
  • Processor (CPU) : Intel(R) Core(TM)2 Duo CPU T6670 @ 2.20GHz
  • Processor Speed : 1,200.00 MHz
  • Total memory (RAM) : 2.8 GB
  • Java : OpenJDK 1.6.0_0 64-Bit

The following test configuration is applied :

  • Concurrent worker Threads : 200
  • Test repeats per worker Thread : 1000
  • Overall test runs : 100

MS Open Tech’s First contribution to OpenJDK


MS Open Tech’s First contribution to OpenJDK

This means that in a not so distant future Java applications on Windows will see value from a serious performance increase for distributed cloud scenarios, especially when using Hadoop and other systems that rely on fast communications via distributed processes. This code was developed as a result of requests from some of our partners, and it enables Java sockets to take advantage of Windows’ TCP Loopback Fast Path capability, which speeds up the communication between sockets that are on the same machine.

We want to thank the OpenJDK community for their help and guidance. We want to especially thank Alan Bateman of Oracle who offered to be the sponsor of this contribution. His invaluable assistance and advice helped greatly in our first successful steps as OpenJDK contributors. We are looking forward to future collaboration opportunities and hope that this is one of many successful contributions in the future.

This contribution is another important step on the journey we began last year with our partnership with Azul, which has produced Zulu, a certified and supported Windows 64bit version of the OpenJDK, made available on the Azure platform. In 2013 we also integrated the deployment of Zulu on Azure into our Azure Toolkit for Eclipse. This new Java code contribution continues our plan to make high-performance Java support on Windows and Azure flexible and simple.

We’ve also developed additional resources to support Java developers on Windows and Azure:
