Plugin Slows Down All Backend Navigation

Hello Team
When this plugin is activated, navigating between areas of the backend dashboard, e.g. clicking on Settings, Plugins, Users, Pages, etc is extremely slow, sometimes it takes up to 60+ sec to have the next page fully loads.
When it is deactivated though, things go back to "normal".
Is this a know behavior?
It is affecting productivity and effective usage of other aspects of the dashboard.
