Summary: From the folly format docs > Use fmt::format instead of folly::format for better performance, build times and compatibility with std::format eden build times have gotten a bit high, cutting out folly format will help reduce build time, so let's start by banishing it from eden see the last change in this group for the difference Reviewed By: xavierd Differential Revision: D38251002 fbshipit-source-id: 41559edc44157f64950e764fb3bc941739dcbf40
