<div>Hello,</div>
<div> </div>
<div>On my Application I currently am using two layers to draw my roads. The first one is a line layer that draws the road itself. The second is a annotation layer that draws the labels and the road shields. Both layers have the same source dataset. My
concern is that my application is taking a performance hit since the road file is being read twice.</div>
<div> </div>
<div>If there is a performance hit by reading the same data file twice, is there a way combine the line layer and annotation layer into a single layer that has both the road symbology, and labels that have shields?</div>
