Apparently they didn't measure the right configuration of the double-conversion library. (Which they confirmed in a private email). My current understanding is, that grisu is still 1.7 times faster.
They promised to update their talk, PDF and web presence.

@floitschG If that's was the case, then we could replace Dragon4 with Errol3

We could, but I'm not sure it's worth the effort: dragon is only hit for very few cases, and the code is well tested.
In any case: I would like to see the new measurements first.

Another option worth considering:
The Swift standard library is now using a fast algorithm that combines features of Grisu2 and Errol4. The C implementation includes detailed comments. The original pull request has some additional discussion and explanation.

Closing this issue. Ryu is superseding both Errol as well as Grisu.
