title: Dev browser load time slow - decrease vendor.js file size?
body: <p>Using Angular 8.0, </p>
  
  <p>My browser load time with ng serve is about 15 seconds.</p>
  
  <p>My browser load time with ng serve --prod is about 4 seconds. </p>
  
  <p>In of the main differences that I see to cause the slow load time in dev is there is a vendor.js file that is 7 MB large. </p>
  
  <p>What can be done to make the browser load time for dev less and closer to what I get to the prod build? Could some kind of modification be done to the tool chain where the vendor.js file is smaller?</p>
