Chrome is known for memory consumption but there are things you can do to help better manage and monitor your configuration for current and potential future issues.
Similar to windows task manager there is a built in task manager for Chrome, launched when you press Shift-ESC. Within this area, you can identify problematic tabs and/or extensions consuming too many resources. With this knowledge, you can decide how to manage your running configuration, or kill out of control tabs and extensions.
This will not help with network or site issues within the webpage itself. To better understand this area, you can launch DevTools from the specific tab itself. I suggest that if you notice an out of control site, you can then use the DevTools from that page to better understand why there may be a problem, if interested.
