The implementations all used pure message passing - no C functions, no IMP caching.
While ObjC may be faster than Java on the benchmarks as well, my original comment was based on real-world usage where ...
1. The language flexibility lets you focus on, and rework the overall design, optimising details *late* 2. In ObjC it's trivially easy to drop back to plain C in critical sections, so you can perform additional optimisation
... which (in my experience) means that for large, complex applications ObjC works out faster than C++ despite the fact that C++ is much faster in specific benchmarks.
