    For instance, for cp-demangle.c, the older allocator does this on
    demangle_special name:

This had 54 spills.

    The new one does this:

It has 90 spills.

So I'm not sure what you are showing.

    Would it make you feel better if i just said it performs " a ton" better
    or some other vague, not applicable at all term?

It would actually be good if you could quantify the performance improvement.
You could compare the static number of memory spills/fills, the number or
register-register copies, or performance of test cases, perhaps even SPEC.
