Does Using Taboola with Adsense drops Adsense Revenue and Site Speed?

Do you guys suggest Taboola with Adsense?
If yes, does it affect anything related to site… like Adsense Revenue drop or Site Speed, etc…

Test once with and without advt

Not a conspiracy theory, but I feel that Adsense revenue drops when you use some other ad network along with it on your site. I might be wrong though.
