Barring any bugs, the hope is that the code generated on Windows and Linux for the same architecture will be very similar, modulo calling conventions and ABI.

Then you come down to issues like Linux networking vs. Windows networking, Disk I/O differences which are interesting but from a .NET perspective less so in my opinion.

It is very interesting to know if running .net core on Linux gives you better performance than on Windows. If you don't get any perf. penalty then moving to Linux saves you a lot in Windows Server licenses! And if Linux is faster then there is really no reason to stay with Windows Server anymore.

Bing is Microsoft, they likely do not pay for Windows licensing, and would also rather work with the Windows team than switch to Linux.

Of course Microsoft won't. THE outcome of the performance comparison is important for all the other companies using .NET.
