Have you ever wondered on what operating system Java works the best? While by no means is it a conclusive multi-platform comparison, for this article we ran a number of Java benchmarks on both Windows Vista Premium and Ubuntu Linux to see how the Java Virtual Machine performance differs. In addition, when running Ubuntu we had tested Sun's official Java package as well as the OpenJDK alternative.
For this round-up we had used a Dell Inspiron 1525 notebook (PM965 + ICH8M Chipset) with an Intel Core 2 Duo T5800 processor clocked at 2.0GHz, 3GB of DDR2 memory, 250GB Hitachi HTS543225L9A300 HDD, integrated Intel 965 graphics, and a screen resolution of 1280 x 800. On the Windows side we were using Windows Vista Home Premium SP1 while with Ubuntu we were using Ubuntu 8.10 and the stock packages (Linux 2.6.27 kernel, X Server 1.5, etc). Each OS was left to its default settings, including the use of the standard desktop effects.
