This blog describes how to build both, a 64-bit and a 32-bit version of OpenJDK 8 on a plain, vanilla WindowsXP 64-bit operating system using only free (as in free beer) tools.

This blog discusses the main differences between the C++ and the Template Interpreter which are both available within the Hotspot sources of the OpenJDK project. Some performance tests with the DaCapo benchmark suite which compare the two interpreters in mixed and interpreted mode on Linux/x86 and Solaris/SPARC conclude the presentation.
Recently I did some benchmarking with the HotSpot and because my program was obviously too slow, I began to browse the HotSpot sources for some secret tuning parameters that could save my day. And indeed, after some digging, I found a real big fish: the "-Xintelligent_as_can_be_execution" option.
