1.11. How to optimize Web Map performance

Web Maps show data rendered by the server. The more of this data you have, the more server resources are needed to render and the more time it takes. There are several techniques you can use to improve your map experience.

Don’t show everything at once

This is a universal recommendation. Does your user need to see everything after opening the Web Map for the first time? Typically, it is not informative. On broad scales (smaller zooms) it is advisable to show limited amount of data as a start.

Scale range

Set a range of scale levels for displaying data on a Web Map. This will allow you to avoid requesting data outside this range and showing excess data where it is not essential.


Set up caching for your layer styles. In this case, already rendered data will not be re-requested.

Select Image as an adapter

In the Web Map settings, go to the Layers tab and select Image as an adapter to allow for faster data processing. We do not recommend using Tiles if it isn’t necessary. It slows down the entire Web GIS if large amounts of data are used.
