Optimize data used in QGIS project

[xycarto]

Speed is an issue when exporting the image out. Creation of the tile image can take several minutes depeding:

1. The properties setting for the layer in QGIS
2. Indexing of the layer. Large layers could use an index
3. The file types, like GPKG, SHP etc.

Potential solutions

• Look back the the QGIS project and remove complex draw functions on the layer
• Index all the vector layers
• Switch to using Flat Geo Buff (https://gdal.org/drivers/vector/flatgeobuf.html)
