Ubuntu – Why does chrome use excessive amounts of CPU

14.04cpugoogle-chrome

Synopsis

For the past few weeks, i've really started to notice a process on my machine hitting the CPU. So today I have taken a look into it, to find that Chrome is running about 100% CPU.

  • Is there any known bugs that may explain this? Or
  • Is there a method for me to resolve this?

I do not have any extensions installed, it's a recent clean install with no extensions.

Best Answer

Use Chrome's built-in task manager to see what part of Chrome (page, plugin, etc) is using CPU.

To access it, just press Shift+Escape (or right click the window decoration and select Task Manager)
