A patch to the code would be preferred; or at least a profiling of the behavior to identify the locations where the time is spent. It sounds like some nasty o(n**2) or o(n**3) algorithm issue. Everyone on the development team has a long list of things they are working on - so unless someone adopts the problem or someone provides a patch, it's likely to remain slow.
