Performance gains of the new C implementation are between 12x and 80x, depending on the application.

As a Python user, this looks really cool, thanks!

As a packager, is the libmpdec library used elsewhere? For Gentoo, we generally prefer to package libraries separately and have Python depend on them. From the site, it seems like you more or less wrote libmpdec for usage in Python, but if it's general-purpose and actually used in other software, it would be nice if Python grew a configure option to make it use the system libmpdec.

Cheers,

Dirkjan
