If you have more performance hints, I'll gladly take them :).

Using a cpu that virtualizes the mmu in hardware helps tremendously.

PPC never does that. Even with the virtualization extensions the MMU is
still software managed.

Then mmu intensive loads can expect to be slow.

I was also more thinking of hints like
"kmem_cache_zalloc is slow" or so ;).

Stuff like that is usually worthless. To give real feedback I need to understand the hardware, so I'm reduced to coding style and indentation review.
