Right - boost::units is supposed to be a zero-overhead abstraction buy there are still edge cases where the compiler can’t optimize away all the template wrappings. Generally still worth it, if you find a performance bottleneck you can move back to doubles and conventions to keep the units straight. This sounds like it may not be so easy to selectively opt out of.
