 The opened HTML page displays the reference distribution of the heap memory. You can choose to view the "inuse space" or "inuse objects".
 
-For example, the heap profile sampled from a Kitex RPC service is shown below, which reflects the call stack distribution of object creation. The largest proportion, FastRead, is the function for object deserialization.

 By using the goref tool, you can see the memory reference distribution of heap objects reachable by GC, thereby quickly pinpointing the actual code locations holding references.
