We are experiencing slow load times for our hosted Web AppBuilder application.  We have downloaded and customized, built widgets, and uploaded to our server, and upon viewing the application via browser, the application loads very slow 5 -10 minutes. 

Is there a way to speed up the initial load time?

At the Dev Summit last week, there was a session on advanced topics for Web AppBuilder development and the video of the session will be ready soon (see this post). During the talk, they went over techniques for creating a build of the WAB for production that speeds up the initial load. The repro for this build is here.
