With Java and OpenSolaris being products of Sun Microsystems, it shouldn't be too surprising that the fastest Java performance was generally witnessed atop this Sun operating system. In the Bork file encryption test, OpenSolaris had a very strong lead over Ubuntu and FreeBSD. With the Java SciMark test created by the National Institute of Standards and Technology, OpenSolaris exhibited the best FFT and Monte Carlo performance. Ubuntu managed to take a close lead in the Sparse Matrix Multiply performance for Java SciMark and then the SOR performance was too close to call between the three test operating systems. The last Java-powered test was the Sunflow Global Illumination Rendering System, which is built around a ray-tracing core. Here the best performance was found on FreeBSD 7.1 Beta 2.
