More Fedora/Ubuntu Linux vs. OS X OpenGL Benchmarks

Earlier this week I shared some new OS X 10.10 vs. Fedora 21 vs. Ubuntu 15.04 benchmarks, which were quite interesting and Linux ended up having the upper-hand on this new Mac Mini with an Intel "Haswell" CPU sporting Iris Graphics. For those interested in more cross-OS benchmarks with Intel Iris Graphics, here's some additional results.
