Monte Carlo was also faster in our newest tests.
Ending out today's benchmarking, the overall composite performance in Java SciMark was up with Ubuntu x86_64.
As you can see from the results, using an Ubuntu 9.04 64-bit installation is much faster in some areas than Ubuntu 9.04 32-bit and it makes Linux more competitive with Mac OS X. However, there are still a few areas where Ubuntu Linux performed badly compared to Mac OS X 10.5.6: graphics, file encryption, SQLite, threaded disk reads and writes, PostgreSQL, Sunflow ray-tracing, and Bork file encryption were the key places where Ubuntu continued to struggle.
