Answer
Eden Space is for short-lived objects; Stop-The-World freezes execution for GC.
In JVM memory management, the Eden Space is part of the Young Generation where most objects are initially allocated. It is designed to handle short-lived objects, which are often discarded quickly. However, during a 'Stop-The-World' event, the JVM halts all application threads to perform garbage collection, impacting performance. For example, in a web server handling thousands of requests per second, a 'Stop-The-World' pause might lead to noticeable delays, making it critical to optimize object creation and lifespan.
