The Haswell architecture has a new AVX2 instruction set that's supported by more current versions of gcc and visual-studio compilers. In-memory databases are known to benefit substantially from the incorporation of these instruction sets.

It would be great to have linux and windows packages with these already compiled. Notably aptitude and windows packages.
