The SRTM map is displayed in the Map View when it's selected in the map provider list, this is described here.

The map is not loaded from the internet, it is painted in the application and is based on SRTM data. It draws the same elevation with the same color but the color for each elevation can be customized.

Before the map can be painted, the SRTM data needs to be downloaded from the internet and are stored locally at this location to reuse it when the same location is painted again.

The downloading status of SRTM data and other tile infos are displayed in the map info toolbar.

Use Offline Map

It is recommended to use the offline map feature, which is described here because painting the map is CPU intensive and only a few images are cached in memory.

Using offline images slows down a little bit the creation of the map tiles but already computed and saved map tiles are displayed much faster.
