The difference is in your file you still have the `Widget widget` parameter, whereas your faster version has the `const Widget& widget` parameter. That's what matters. ETA: there is a slight advantage for your function body using GNU libstdc++, but there is no advantage when using LLVM libc++. Under libc++ all three are exactly as fast, and faster across the board than any of the GNU results. | ||
