JavaScript Memory: Heap, Native, WebGL/GPU

Question

Is it possible to see all sources of memory for JavaScript in Chrome? As far as I know the three above are what would be available.

The Heap is your basic GC-able JS objects. "Native Memory" is not part of the Heap .. like DOM, TypedArrays, 2D context ImageData and so on. WebGL too is a source of memory.

I'd like to know how much my code is using. Chrome recently dumped their Native profiler. Heap profiling is simply not sufficient for large memory web-apps.

Is there a way to get useful information on what percent of these memory sources my code is using?

Answer 1

I estimate the native memory by using the chrome task manager (more tools | Task Manager). It shows the private memory, GPU memory and javascript memory. private memory - javascript memory would be an approximation of native memory. But it can't indicate how much memory is allocated by different kinds of resources.

It also shows the GPU memory if the page has a canvas.
