Heap Size Optimization: Adjusting the size of the heap can significantly impact GC performance. A heap that is too small can cause frequent GC cycles, while a very large heap may lead to longer GC pauses.

Generational Hypothesis: Java’s heap is divided into generations (young, old, and permanent). Understanding the allocation patterns of your application can help in tuning the sizes of these generations for optimal performance.

GC Logging and Monitoring: Using tools like JVisualVM or GC logs can help in understanding the behavior of GC in your application, identifying issues like frequent or long pauses.
