Paolo Carlini <paolo.carlini at oracle dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |paolo.carlini at oracle dot com --- Comment #19 from Paolo Carlini <paolo.carlini at oracle dot com> --- I ran some quick tests and indeed the performance seems equal of better of those of the old C++03 code. Note that the patch is very small and can be installed even on top of the installed headers, without rebuilding anything, thus I would really encourage the bug submitters to test it and report back.
