Oh wow, first ever report about Windows builds being faster than Linux
ones. That's a good start of the day.

In any case, it's not that much we can do with only timing information. We
have to be able to reproduce the issue ourselves in order to investigate
it, so regular bug report guidelines applies:

- Provide as much simple .blend file as possible which still indicates the
problem (2hrs render is not really good showcase)
- Provide system information (Help -> System Info in Blender (having both
Windows and Linux system infos will be handy))

Also please check you aren't using some power/performance policy on Linux
-- if it lowers CPU frequency down to lower power consumption we can't do
much form Blender side.
