是否收集了大对象堆

Question

I cant find information about Large Objects Heap. Everywhere is wrote that it isn't fragmented. But I heard that isn't collected.

I cant find some article which provide me this information.

So, is LOH collected (dead instances removed from memory) or isn't?

Answer 1

The large object heap is collected as well. I don't know where it says that it isn't fragmented. That's not true. It isn't compacted by default though.

If you want to override the default behavior you can set the LargeObjectHeapCompactionMode flag, but keep in mind that compacting a large heap can be very time consuming.
