# Using the GC Configuration Page

The GC Configuration page contains configuration data related to garbage collection.

This page contains panels for GC Configuration, Heap Configuration, and Young Generation Configuration.

Using the GC Configuration Page: GC Configuration Panel

- Young Garbage Collector: The garbage collector used for the young generation.

- Old Garbage Collector: The garbage collector used for the old generation.

- Concurrent GC Threads: The number of concurrent GC threads.

- Parallel GC Threads: The number of parallel GC threads.

- Concurrent Explicit GC: Indicates whether `System.gc()` is concurrent or not.

- Disabled Explicit GC: Indicates whether `System.gc()` is will cause a garbage collection or not.

- Uses Dynamic GC Threads: Indicates whether a dynamic number of GC threads are used or not.

- GC Time Ratio: The GC time ratio.

Using the GC Configuration Page: Heap Configurations Panel

- Initial Heap Size: The size of the Java heap at JVM startup.

- Minimum Heap Size: The minimum amount of memory reserved for the Java heap.

- Maximum Heap Size: The maximum amount of memory reserved for the Java heap.

- If Compressed Oops Are Used: Indicates whether compressed Ordinary Object Pointers are enabled.

- Compressed Oops Mode: Indicates the kind of compressed Ordinary Object Pointers being used.

- Heap Address Size: The heap address size.

- Object Alignment:

Using the GC Configuration Page: Young Generation Configuration Panel
