Well I think I am actually pushing the limits here now. I have not found any real difference betwean a list, vector or deque. What I think I really need is a normal C array to speed things up that little extra but since the number of elements in the array are unknown the overhead to expand it would probably be too much (but I will think about it, might have a good algorithm, since it doesnt really matter if I use all the memory or if the actual array is larger than what I need).

Ill give it some thought.
