[Sidefx-houdini-list] Houdini performance on Windows 7 vs Linux

There is a bug in the Linux kernel that prevents Turbo mode (automatic
overclocking of a single core) from kicking in on core i7
(http://bugzilla.kernel.org/show_bug.cgi?id=15064). Sims being single
threaded, that would explain the difference between Windows 7 and
Linux. The bug has been fixed in kernel 2.6.33.

I don't know about phenoms though, I have not used an AMD CPU at work
or at home for quite a while.
