[erlang-questions] Dual core

Hi,

I made a few tests for the utilization of dual core CPU under Windows 2000 with Erlang/OTP R11B5.

It seems that:
- if I start 2 CPU consuming erlang processes within the same Erlang node they use one core only
- if I start those 2 processes in different Erlang nodes then both cores are used reducing the execution time to about 60%

My question is if Vista or OTP R12 brings improvement so that Erlang processes in the same Erlang node would utilize both cores?

Thanks,
Jozsef
