The intended audience is for intermediate to advanced programmers wanting to learn about JavaSpaces. Chapter 8, “Parallel Computing,” looks into some of the areas where you can get into performance trouble and also some of the ways in which JavaSpaces can be an aid to performance.

This should not be a surprising statement to anyone who has had to deal with a distributed programming environment in the past. Add To My Wish List. In javaspaecs, it uses the concept of a linked list to explore some of the differences between distributed and nondistributed data structures.
