from my experience, Gem is 2 times faster on the same computer using ubuntu than osX. thanks to nvidia profiling tools, Nicolas pointed that gem is limited to 50% usage of the GPU. there is certainly a limitation somewhere on osX preventing application to use full performance of the hardware. so, you applications are slower, but the interface will always be smooth...
There's a setting in Gnome/Ubuntu for choosing no effects, normal effects, extra effects. This may make a difference. What kind of performance difference do you get when you change that setting ? It might explain part of what happens on OSX, perhaps (where, afaik, you don't have such a setting, and effects level is somewhere between ubuntu's normal and extra levels).
Yep, of course, you have to choose 'no effect' in 'Appearance' to get best frame rate. MacOSX should have this option too. ++
