I seem to recall from my compsci classes some years ago :-) that you generally trade insertion speed for access speed. That said, it seems that your basic data structure maybe should be a "traditional" (not perl) hash. That is: buckets that hold multiple values. a hash function. You could then make the structure of the buckets be arrays, trees or dequeues depending on what your incoming data looks like and so forth. With the small size, arrays are likely to make good buckets. I say that because if you mke 1000 buckets, there will be few collisions. You should also store the size of each bucket in order to make the distance computations fast.

Why is "binary search" important for find? The hash, of course, does not provide that at the highest level, but could within the buckets. The hash is likely to be faster than the b-search.
