On the jack site, under documentation, there's some links to 
academic papers regarding jack2.  You may also find some on 
the wiki.

Long story short:

If you're running ONE Jack app -- no difference.

If you're running multiple Jack apps with somewhat 
independent audio chains -- you can get parallel 
processing between the the applications.  To take advantage 
of all 4 cores you would need to be running four apps (e.g. 
Ardour + Hydrogen + a synth + another synth).

Strictly speaking, this has nothing to do with plugins. 
Plugins happen inside the application and Jack has nothing 
to do with them.
