Victor, The Intel compiler produces up to 2X faster code than GCC, on the same hardware. I haven't had a look at performance of VC++ though. But it's something to consider, the stock GCC doesn't produce really good code for modern Intel/AMD processors.
This is a Linux list, but Linux is not magical. You will not see any major performance improvements by switching to Linux, more so if your application is primarily CPU-bound. The advantages o Linux are really in the areas of licensing, flexibility (source available), and perhaps scale-out: it's easier to manage a Linux cluster than a Windows cluster, just because Linux is far easier to script and administer via CLI.
