Google Chrome slow and lags due to Efficiency Mode in Windows Task Manager [Fix]

After a recent update in Windows, new features “efficiency mode” is added where task manager can optimize the process or apps. But this feature seems to kill performance of Google Chrome and after this the Chrome has become very laggy and slowed down significantly.

Task manager on windows desktop  says that efficiency mode is active for certain but not all sub-processes of google chrome but this seem to hinder the Google Chrome a lot more.

Disabling the  efficiency mode for each individual sub-process works for sometimes, but it returns a few minutes later. Some users are suspecting it to linked to Chrome only as

“Switching to Edge is exactly what Microsoft would like everyone to do.  It’s hard not to wonder if this “efficiency mode” problem isn’t designed to sabatage Chrome users.”

This is annoying issue as the “Efficiency Mode’ locks up Chrome  every minute or so for 5 to 10 seconds. Every single “new” tab load takes a lot more time then previous.
