I haven't seen anyone test for kernel performance regressions on m68k
(other than the scheduler regression) -- let alone work on reversing them.
Probably because of the usual shortage of skills.

You have to pick the right architecture. In Linux (the kernel) algorithms
are tuned for the common case, which is x86. And hence you'd expect a
Linux operating system's performance to be competitive with any equivalent
operating system running on that architecture.
Having said that, kernel performance even on x86 is quite variable from
one release to another:

Of course, benchmarks on Intel architectures should not be taken as
representative of m68k performance. It would be informative to build and
run a benchmark suite like that one on debian etch-m68k (it has gcc 3.3
and 4.1) using the latest kernel.
