Correct me if I'm wrong, but I think some important optimizations (like inlining) are performed in the front end. It's pretty obvious that DMD's inliner needs improvement, though I agree with Walter's decision to prioritize this below fixing major bugs, 64 support and (before that) finalizing the spec. Therefore, the performance of GDC is still a quality of implementation issue rather than a fundamental technical issue.
