Does Server Collection Create A Seperate LOH Heap For Each Core? C#

From the research On Garbage Collection, Server Collection Allows for the creation of a separate thread for each CPU core that you have that runs a separate GC and Generational Heap. But I Wasn't Able to find anything On whether each thread gets its own LOH Heap Or There Is Just One LOH Heap Per App

    The following are threading and performance considerations for server garbage collection:

    • A heap and a dedicated thread to perform garbage collection are provided for each logical CPU, and the heaps are collected at the same time. Each heap contains a small object heap and a large object heap, and all heaps can be accessed by user code. Objects on different heaps can refer to each other.
