That's the sum of all the timers from below, this module does not make the site slower. That table is misleading because it displays on top the first method that calls the full page. To know what is causing the slowning down you need to disable it and reload the same page to find the right method that causes that. In some versions video, audio and image transcoding is causing the slowing down. The latest version the UNA.io team improved this, if you have latest version then it might be another module who is transcoding images on the fly and not using the built in methods, if that's the case maybe the timer of such methods are not being registered by the profiler app.
Also we did refund the money to your paypal account for this and the other 4 modules because you stated you were quitting UNA.io, so please uninstall and delete all our 5 modules from your website or buy another license of the ones you need in case you are planning on keep using them.
