Microsoft Visual C vs Gcc on Windows

..just seeing if I can squeeze some extra performance, so I'm taking a look at gcc.

When it comes to performance using these compilers, what are others finding? Also, for gcc what optimisation flags are folks using? For reference, I am using -O3 and -march=native

PGO can also produce faster binary with gcc.
