[EnergyPlus_Support] Runtime: Windows vs Linux



In testing the recent version 2.2, it seems the runtime
discrepancy between the Windows version and the Linux version
remains.  On the same hardware, I see the Windows version
running about 20% faster than Linux.

Any idea if this is a result of compiler differences?
Different compiler options?  Math libraries?  Any hope
of rectifying the Linux speed penalty?

We do runs by the thousands on a Linux cluster, so a 20%
improvement would make a huge difference.
