Sun Java vs. C#
By dagastine on Jun 19, 2006
Here's my latest round of platform performance comparisons using Scimark. This time I compare Java to C# and once again Java performance is looking quite good. Thanks to Tony Zhang, another colleague of mine on the performance team who ran the initial performance comparision a few months back and provided me the environment to re-run the tests with our latest JVMs. The system under test was a 4 CPU Intel Xeon MP server (4x2.78 GHz, 8 cores, 3.87 GB memory) running Microsoft Windows 2003 Server and .NET 2.0. The CLR version under test according to SciMark was 2.0.50727.42. We used the Scimark 2.0 C# port found here. The HotSpot server compiler (-server) was used for both J2SE 5.0_08 and Java SE 6 b87. SciMark was run with the large data set (-large). Also, I found the chart below in an interesting writeup showing similar performance comparisions with older versions of the JVM. I particularly like HotSpot's performance lead over JRockit.
