Chrome Heap Snapshot - Why it doesn't show all the memory allocated?

update

there was native memory snapshot that was able to show you the native memory graph.Unfortunately we removed it because it was a fragile piece of code. It required nontrivial instrumentation in hundreds of classes and affected the binary size.I hope we reimplement it later.

It takes a snapshot of Javascript heap. All your javascript objects use 7.5mb. This size doesn't include images, canvases, audio files, plugin data, etc.

There is a native memory snapshot in DevTools.It counts non-javascript memory used by the renderer process but this is an experimental feature.

You need to enable DevTools experimental feature in chrome://flags, restart the browser, enable Native Memory Profiler experimental feature in DevTools settings panel and reopen DevTools.

After all these steps you will be able to take Native Memory Snapshot in Profiler panel.Not all the memory chunks in the native memory heap are counted but we are working on that.

Please use the Canary version of Chrome.It updates every day and works side-by-side with other versions of Chrome.

If your page eats gigabytes of memory and has big "Other" bar, more than 10%-20%, please drop a mail about that to the Google Chrome Developer Tools Foums.

You can still take snapshots under the profile tab and click take head snapshot which gives you in-depth memory usage stats.
