Hi, I have what I think is a really strange problem. I have a fair sized problem, which involves sorting a data set, first on labels (which are Strings) and then on scores (which are Ints). The strange thing is that string sorting is *vastly* faster than int scoring! Now, I've tried modifying the sorting routinges, moving them into the same module, and so on, to no avail. Is there any likely explanation? The pipeline is basically sortBy int_cmp . compound_equal . sortBy string_cmp I hesitate to post the code, since it's part of a rather large program, and in the hope that somebody will pop up and say that oh, yes, it's a well know feature of 'sortBy'. Or that it's an artifact of profiling. Or something like that. Any, and I mean any, suggestions really, really welcome. -kzm -- If I haven't seen further, it is by standing in the footprints of giants
