Hi This is very interesting. I have been trying to debug memory-comsumption lately as well, though I have used different methods:
I guess this API is to make the data available in web-inspector right? I have gathered similar data using valgrind's massif which can tell you which objects have been allocated, when and where and how much memory they use, but massif is very slow and can require some perl-processing afterwards to get good data out off. Lately though, I have been using a different system. like many undocumented secrets in WebKit, there are a series of memory statistics functions for the various memory subsystems. Take a look at Source/WebKit2/Shared/mac/WebMemorySampler.mac.mm for some examples of what it can tell you. It doesn't tell you how large the elements of the render-tree are, but the render-tree is not that that significant anymore, but it tells you how much is allocated for JavaScript heap, stack or pre-compiled code separetely, and how much is used by various caches, and how much can be garbage-collected if you have a memory pressure handler to trigger it. This has been very useful to me at least. I can see how this new system is more powerful, but I can not help to feel it is somehow doing the wrong thing at the wrong place.
