Yes, but before making your app more complex by using multiple
processors you might want to make sure it's CPU bound. Otherwise,
more processors may actually make it slower.

Thanks guys for the help. Steve, the thing is, this is not for one app, but for a container to
hold/manage multiple apps. Think Tomcat or the like. Jeremey reccomends running each
app in its own vm, so that would, I believe, let the system decide how to schedule the apps
and let them each take advantage of one processor which could be ok. I'd lose to some
extent some central management of resources, etc. unless I have a controlling process,
and if one app had significantly greater performance needs I suppose I'd need to spawn a
new copy in another container and figure out how to join state in those two containers.

Basically, trying to figure out in Io, what's the best way to scale with multiple Io webapps.
Maybe by using multiple processors is not the answer ..
