If boost-regex is better, should Ubuntu switch to it as the default std::regex provider? Such that anything built on or for Ubuntu uses the faster implementation?
As a user of Ubuntu, I would certainly prefer if the faster implementation was used (which is Boost.Regex). That said, I think it's not so much a choice of Ubuntu (or Debian) package maintainers but rather that of the upstream projects. Somewhat on that note, just recently I (among other users) reported a KDE performance bug[1] which appeared in the latest Kubuntu and turned out to be caused by std::regex. The currently proposed solution is to replace it with a manual parser. [1]: https://bugs.kde.org/show_bug.cgi?id=414036
