No two data sets are the same and each will have different impact on map rendering performance.
Whilst in general larger data sets can take more time to render there are other aspects
of data that also have an effect:
- The number of records in a table that are visible and within the map view.
- The complexity of the map features (a simple building outline with 4 nodes will
render quicker than a river flood boundary with 100,000 nodes).
- The projection of the data (data that needs to be re-projected to align with
base mapping will take longer to render).
