In the case of std.algorithm.sum, the focus is on accuracy
rather than performance. It does some extra work to ensure
maximum accuracy in the result, so it shouldn't be expected to
have top performance. Granted, though, the docs could be
clearer about this accuracy vs. performance tradeoff. Please
file a bug on this (or better yet, submit a PR for it).
In any case, 4 times slower sounds a bit excessive... it would
be good to investigate why this is happening and fix it.
I think you'd be good at reviewing this:
