Answer
Eden space is for short-lived objects; tenured is for long-lived.
The Eden space holds newly created objects. Most objects die young and are collected here, which is efficient. Surviving objects are moved to the Survivor space, and eventually to the Tenured generation if they persist. In a web application, temporary user session data might reside in the Eden space, while persistent cache data moves to the tenured generation.
