QT Signal speed isn't the problem. Focus on making your app fast. Then if that's not enough, make it appear fast. If your report generator takes 5 seconds to generate 400 pages, don't put up a meter to show percentage done. Instead, start showing the user the pages that have already been generated. They won't care that there's 2 more seconds to wait, because they can already start seeing pages.
