Thanks for your answers.
Now, it seems that if the items passing between the map phase and reduce phase are many and small, then the system could benefit from a "chunking" fitting that collects items and sends them off in a list to the next fitting, after receiving X # of items, or after some timeout (say, Y ms); i.e. basically Nagle's algorithm Otherwise, we may get burned pretty seriously by the "sync send" that happens between fittings !?
