What is the reason for dividing the managing memory into areas for large and small objects in the garbage collector?

In the garbage collector in C# (CLR), memory is divided into regions for small and large objects to optimize performance and memory management. Small objects (Small Object Heap, SOH) are usually allocated and freed quickly, so they are placed in the heap, which is often subject to garbage collection (generations 0, 1, 2). Large objects (Large Object Heap, LOH) are objects larger than 85,000 bytes, allocated separately to avoid frequent copying and moving during garbage collection, as moving them is costly due to their size. This division allows:

• Reducing overhead for managing large objects.
• Decreasing memory fragmentation.
• Increasing garbage collection efficiency, as LOH is collected less frequently.

Thus, dividing memory into regions for large and small objects helps optimize the garbage collector's operation and improve application performance.
