Question: Solution to Google Chrome (Helper) using lots of ram and cpu on mac osx
Some people have many google chrome tabs open, and this is using up lots of ram. It also causes the fan to go crazy sometimes. I searched for a solution for ages, but no solution helped, until I came across the simple solution of using a google chrome extension which hibernates unused tabs. The problem has now totally gone away.
There are a few differnt extensions which will hibernate unused tabs, but the only extension that has enough setting options to make it do what I want, is called “The Great Suspender”.
You can set the time after which the tab is put into hibernation (sleep). The tab automatically unsuspends when it is focussed on, (i.e., you don’t need to then also click on a specific button). And the hibernated tabs will stay in hibernation after you restart the computer.
There are many other settings that can also be tweaked. (After making any changes, remember to click the “save changes” button.)
Hope this helps.
