 * Once UTM HANDLE is enabled the CF Edge cache is bypassed causing significant 
   drop in performance.
   This never happened in earlies versions.We are using the
   free one.

 * Hi [@wowwephraim](https://wordpress.org/support/users/wowwephraim/) 
   Unfortunately
   there is no good solution for this in the free tier. Because V2 ONLY leverages
   server side cookies and it is being set there. In your case, server might be 
   invalidating the server side cookies, therefore it resets on every page visits
   degrading the performance. I recommend you to upgrade V3 and use this feature
   [https://docs.utmgrabber.com/books/102-getting-started-for-handl-utm-grabber-v3/page/disable-server-side-tracking](https://docs.utmgrabber.com/books/102-getting-started-for-handl-utm-grabber-v3/page/disable-server-side-tracking)
   We’ve designed this for sites like yours! Lmk if you have any questions, happy
   to explain more
