>From profiling, I think the single biggest speed up that could be done for DateTime, when using an Olson DB timezone, would be to implement Tree::RedBlack in XS. Even better would be to implement a custom red-black tree that natively worked with the kind of weird values that are fed into (complex data structures as opposed to scalars). This would be a huge win for anyone who had to work with time zones.
