there has been some discussion about this in June:
What I gather from the conversation is that there is a global disk IO
lock which leads to performance degradation in disk IO intensive
applications, however there are plans to improve the situation.
If I had to make a wild guess, I'd expect that the process ring
benchmark would scale almost linearly with the number of processors.
The last thing one knows in constructing a work is what to put first.
