I don't know about other OS X technologies, but IIRC CFMessagePort is
optimized to exchange large amount of data between processes.

Thanks, Marcel and Graham. It answers my question. I will now look for
ways to optimize data transmission between processes, and I think I
have already found one.

I haven't tried either of the methods I mentioned so far (because

lazy, sorry:), but what I have tried is I created NSData from the

had to force-quit the process.
Yes, NSKeyedArchiver is not really suitable for large data-sets.
That's why I am asking if the same
thing is going to happen with piples and DO? Or maybe I'm doing
something wrong?
Well, the two questions are really orthogonal: both DO and pipes
will
require serialization if you actually want to move the object across.
By "large" I mean about 10-100 MB. I don't think I am going to hit
the
boundary of VM anyway.
Can you tell us a bit more about the object in question? Is it
really one
object with 10-100MB of associated data? What's the data and how
is it
encoded? Or is it an object graph with lots of objects involved?
Why do
you want to move the object/data across to another task?
