Besides the point that the two are not comparable, code size results are in the sheet I linked to in the proposal; there's no negative impact. The feature has been enabled by default in OpenSUSE for nearly a year and there have been no noticeable performance issues reported there either. IMO the magnitude of improvement is such that a benchmark shouldn't be a blocker for this feature, but if that's what FESCO insists, I'll be happy to run whatever benchmark they suggest.
