there has been some discussion about this in June:
http://thread.gmane.org/gmane.comp.lang.erlang.general/15639/focus=15643
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.
Goodbyte, Gerd.
