The meta data vs code ratio is 1:1 in the product bits for sparc. The 2:1 ratio I quoted is for x86 code in debug mode where the code is smaller and we keep extra meta data which skews the results. In product mode x86 is about 1.4:1. It's not as bad as 2:1 but there's still quite a bit of meta data in between the chunks of code.
