I have an application where I use React to render an OpenLayers map (using version 3) in order to display a .mbtiles file served from Tilserver-gl-light. The app functions and does what I want it to, but it will be running on an old browser that is not very powerful. When I run the app in my dev environment (latest version of Chrome), it works well. I am looking for any other optimizations that you may recommend for me to try.
