Adobe Animate Question

Hello,

So we have these flash files that are diagrams of parts and the user is allow to hover over certain hotspots and it will display the number of the circle which the user hover over. So we open up the .fla file in adobe animate and convert it to HTML5/canvas. But when we do a command test to make sure the conversion worked and all of the other changes we did it takes 30-40 mins to display in a browse is it because the file is too big?
