In order to speed up loadtime I try to avoid unnecessary loads. In the Google report (and in my html) I see that many unwanted files are loaded, as jquery-migrate.min.js?ver=1.4.1, core-min, mouse-min, button-min, widget-min and more. I am certain I do not need or use them but they cause (among more) a terrible loadtime. I am using theme Twenty Seventeen.
What should I do to avoid loading these jquery-min files?
