OpenSolaris vs. Linux Kernel Benchmarks

The stock 64-bit version of Ubuntu delivered the highest MIPS count with the 7-Zip compression test, but all other Ubuntu configurations had fallen behind Nexenta CP2 RC2, which came in second place.

The HWB color space test ran via the OpenMP-based GraphicsMagick test profile was the fastest on Ubuntu 64-bit while the 32-bit performance between Ubuntu and Nexenta CP2 RC2 was nearly identical.

The best local adaptive thresholding performance with GraphicsMagick was found on the OpenSolaris distribution, but its lead was a mere one iteration per minute. Ubuntu 64-bit fell behind Ubuntu 32-bit.
