Chrome suddenly using too much memory, what's wrong?

I just upgraded my RAM to double what it used to have and for a couple of weeks everything was running great, but now Chrome is eating all of it, I hit 90% use with only one window and <50 tabs open.

When I close Chrome memory use goes down to 15% or less, is like this app is using RAM for the hell of it, since it used to be a little more frugal before.

What could be causing this?


Solution 1:

Press Shift+ESC in Chrome. This should show per-tab (and per-process) information. Is there a single tab that's using an unusual amount of resources?
