The C-Ray multi-threaded ray-tracer was noticeably faster when using the 64-bit Linux build.

The MP3 encoding performance was also better with the 64-bit version.

While the Linux gaming performance with the Intel HD Graphics on Mesa was about the same, for nearly all of the other computational tests the 64-bit version of Ubuntu Linux continued to offer superior performance over the 32-bit Ubuntu build, as expected.
