Compiler optimisations

[Jack Hale]

At the moment we are using very minimal compiler optimisations, and no machine specific optimisations. Obviously we don't want to build binaries that won't run on older machines, but conversely, maybe some slightly more aggressive optimisations might be good. -mtune=intel perhaps?

I think users wanting this level of optimisation should be building the necessary libraries themselves inside containers.
