Multi-Core, Multi-OS Scaling Performance

OpenIndiana started to inch ahead of the other operating systems when at four and six cores while running the 7-Zip compression test, but this OpenSolaris-derived OS fell into last when it came to enabling six cores with Hyper Threading. CentOS and Fedora 14 scaled the best when Hyper Threading was switched on while PC-BSD/FreeBSD pulled in between the Linux operating systems and the Sun OS offspring.

OpenIndiana was incompatible with the graphics-magick test profile, but between the two Linux distributions and PC-BSD, the results were tight in terms of its scaling performance. Worth noting though is how the PC-BSD performance dips when using three and four cores. This is similar to the earlier Apache compilation test where its performance also strangely scaled poorly with three and four cores switched on.

Again, a dip for PC-BSD at three and four cores, but when maxed out with 12 logical threads, PC-BSD was slightly on top.
