I'm not really sure whether this can be put exactly that way.
On a machine with 4 GB RAM you can spawn about 80.000
goroutines (aka green threads). Let's say each threads
calculates a large fibonacci number. If the fibonacci
calculation yields the processor frequently all 80.000 run
seamingly in parallel and return their result almost "at the
same time".
With GPars this would not work. You can only start some 2.000
Java threads on a machine with the same amount of memory. If
also the fibonacci calculation in Groovy/GPars yields the
processor, using GPars the first 2.000 fibonacci calculations
will nevertheless crowd out the following 2.000 threads of all
those 80.000 fibonacci calculations and so on. I once tried
this out with both Go and Groovy/GPars.

What about using a JVM with green threads support or Quasar,
wouldn't it be more comparable?
