There are a few other things that might help that case.

1) We could try updating the version of double_conversion we have to the latest release. Not sure how long it's been since we last pulled in anything, so there might just be free wins there,

2) There are other libraries and papers that focus on the float -> string case:
- https://github.com/abolz/Drachennest/
- the MSVC STL has a supposedly very fast version in std::to_chars (https://youtu.be/4P_kbF0EbZM is a fun talk if you are into that kind of thing)
- https://news.ycombinator.com/item?id=24917659 has some additional discussion
