comment Partitioning a list when the cumulative sum exceeds 1
I quickly realized that Internal`PartitionRagged was a bottleneck. I then realized the foolishness of my earlier comment about "a simple procedural loop in Compile" when I tried to get around it, for the reason you mention.

comment Why is Random faster than RandomReal?
I seem to recall this being discussed before but my search skills and memory are failing me. In my opinion since the new functions are optimized for generation en masse, and support multiple PRNG methods, it seems reasonable that they have a moderate overhead for individual calls.

comment Why is Random faster than RandomReal?
Random uses an older and poorer PRNG algorithm. Let me see if I can find some references.

comment Evaluation of Alternatives
"We have some improvements in the pipeline and ideas on how to completely clean this up, but unfortunately completely squashing all these issues is a ways off." I am really happy to know that development continues on the core functions, and not only on library extension.

comment Evaluation of Alternatives
"Beyond the fact that evaluation may have undesired side effects, we would have a true circularity problem given that evaluation is done via pattern-matching!" I never thought of it like that, but it makes perfect sense. Thanks for a pithy summary of the evaluation thing.

comment Partitioning a list when the cumulative sum exceeds 1
I just updated my answer with one that's a bit faster, but IMHO not enough faster to justify the ugliness. ;^) I shall try to improve it further.
