So any profile is just a list of the nodes that remain on the heap over a period of time. One would expect that, given proper GC, a heap would remain mostly constant — some memory would be allocated, and then would be cleaned up after it’s done being used.

A steadily growing heap over time, especially during repeated actions, is a sign of a memory leak. You would see this, not with circles of increasing size but rather with the total number of circles increasing.

Finding specific nodes is trickier. I suggest checking the edges and retainers of a node — edges in particular can give clues as to the true nature of the node.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
