[erlang-questions] My frustration with Erlang

[Edwin Fine]

Joel,

What is your hardware configuration? How many cores are available? The
reason I ask is because some people have seen better performance in certain
clustering-type Erlang applications by running one VM per core, each VM
running in +S 1 (non-SMP) mode, instead of using SMP. Have you tried this? I
couldn't figure that out from what you wrote.

Regards,
Edwin
