AMD Shanghai Opteron: Linux vs. OpenSolaris Benchmarks
While OpenSolaris on this eight-core AMD system was faster at the Java-powered Bork File Encrypter test, it receded when it came to Java SciMark 2.0. Java SciMark 2.0 showed that Ubuntu 9.04 had the best FFT, Monte Carlo, and Composite performance while Ubuntu 8.10 had the best Successive Over Relaxation number.
Back in November we delivered Ubuntu vs. OpenSolaris vs. FreeBSD benchmarks using the Phoronix Test Suite. That test system was using the older AMD Barcelona processors, but there it showed OpenSolaris delivering weak performance as well in tests not utilizing Sun's Java stack. Of the 19 tests carried out today, OpenSolaris 2008.11 had just won one of them. In the rest of the tests, the fight was usually competitive between Ubuntu 8.10 and Ubuntu 9.04 for the winning spot. In the end, Ubuntu 9.04 finished first in nine of the nineteen tests.
