After i installed and activated this plugin service, I can see higher RAM and CPU usage in one site. When I'm testing this plugin my VPS RAM usage is 20-25%. After enabled its service RAM usage goes to 75% and server load increased upto 1.5. This is a weird issue.
I have two sites and one demo site (a sub domain site for various WP test before apply main sites). If I uploaded this plugin to my demo site I face that issue. If I use it with active sites, there's no no issue.
This demo site has less plugin than the active sites. But demo site installed plugins are available on the active sites.
