Some people might be quite excited by Milan's work on significant performance improvements to the containers package...
Yes, this is great news - both a well written article and an important piece of work on a cornerstone of the Haskell libraries. But I am also somewhat disturbed that, all this time I've been using Data.Set/Map, AVL has apparently been a much faster alternative, and I never got around to trying it out. Is there a downside to using AVL compared to Data.Set/Map? And would similar improvements apply to it? When performance is starting to matter, it is often because I have large Sets or Maps - it would also be interesting to compare the memory requirement of these data structures. (No matter how much faster a HashMap is, if it exceeds physical RAM it will be outperformed by any structure that manages to fit). -k -- If I haven't seen further, it is by standing in the footprints of giants
