28.5.2. GC Algorithms

Try these first

1. 1.

   What does the Serial GC algorithm do?

   Hint

   Think about the type of applications that may not require high responsiveness.

2. 2.

   What is the primary advantage of Parallel GC?

   Hint

   Consider the processor capabilities when discussing advantages.

3. 3.

   What type of application benefit most from Serial GC?

   • Large enterprise applications
   • Small desktop applications
   • Real-time web applications

   Hint

   Think about the complexity and size of the application.

4. 4.

   True or False: Parallel GC uses multiple threads to perform garbage collection.

   • True
   • False

   Hint

   Imagine a multi-core processor scenario.

5. 5.

   Develop a performance analysis plan comparing Serial GC, Parallel GC, and CMS. Include metrics you would collect and how you would present your findings.

   Hint

   Research each GC's primary performance characteristics.

6. 6.

   Evaluate a real-time application scenario, determining which GC method is best suited and why. What impact could improper choice of GC have on application performance?

   Hint

   Connect performance needs with collecting behaviors of GCs.
