When mobile devices need to make 2x (or 3x for hillshading) requests, that gives a visible latency especially on mobile networks. HTTP2 can help a bit, but it't not yet common.\r\n\r\nI've just checked Mapbox outdoors, and they only serve a single 512x512 PBF which has both vector data, contour lines, and triangulated hillshading all combined. Thus even a desktop browser only does 6 requests for a single map view, which is quite fast.\r\n\r\nIf this can be done on-the-fly via TileServer GL without any performance penalties, then I guess it's a good solution. If this means much higher system requirements / slower serving performance, then I believe an offline processing step would be better."}}
