The C-Ray ray-tracing benchmark really struggles on OpenSolaris with the AMD quad-core workstation, while the best performance was found on PC-BSD and was ahead of Ubuntu Linux.
POV-Ray had not run under FreeBSD/PC-BSD, but between OpenSolaris and Linux its performance was found to be the same.
When it came to Sudokut, an open-source Sudoku solver, its computational speed was much faster under Linux than OpenSolaris / Nexenta Core Platform.
Today's test results show that Nexenta Core Platform 3.0 for the most part performs just like the upstream OpenSolaris build that it is derived from, except for tests involving the GNU user-land that have been brought over from the Ubuntu 8.04 "Hardy Heron" packages. While the performance of these two operating systems is close to the same, it is slower than that of Ubuntu 10.04 LTS with the Linux 2.6.32 kernel in a majority of the tests. OpenSolaris / Nexenta on this AMD workstation were also slower than the PC-BSD/FreeBSD installation in a number of the tests.
