Chrome - Multiple instances running

I am using windows and chrome browser. I only have one chrome window/tab open. My computer is running very slowly, and when I ran task manager, I noticed I have Chrome and Chrome(8) - Not sure if that means 8 instances/tabs are running?

Another problem which happens offen, even when Chrome opens a page, it is not rendered properly and I need to refresh it until it shows the page correctly. Sometimes开发者_运维问答 it simply shows error page. I am not facing the same issues with Edge broswer. Could you suggest a resolution?

As for the first issue - this behavior is by design.

Chrome is built on a multi-process architecture. The browser opens different processes for every tab, renderer, and extension you use.

Google Chrome Browser does not create Multiple Chrome Processes to eat up your system resources. It adopts a unique approach to managing the multiple types of processes that run inside the browser. Chrome also does this to avoid any data loss if any of your tabs crash.

To reduce the number of Chrome processes running on your machine, disable or delete unnecessary extensions.

As for the second issue:

Try clearing out the cache and cookies stored by Chrome from the Settings page
