I'll close this as invalid for now.

GDC-4.8 with 2.064 frontend is still ~30% faster than dmd 2.064 which seems
reasonable. GDC-4.8/2.064 is also ~(3-4) times faster than LDC with 2.063 so it
seems there were indeed some performance improvements with the 2.064 frontend
release.

Anyway, if this is still an issue it's likely an upstream phobos issue, or the
changes in 2.064 have already fixed it.

Feel free to reopen this issue if you disagree.
