Performance issues


Working with SfMaps control, Created 100 markers with data template of image with rotation binding.

Map panning and zooming is very heavy and laggy.

Should we expect improved performance or is this scenario too much for the control?

We have checked the reported “Performance issue on maps” in all platforms. We can reproduce the reported performance issue with large number of markers with MarkerTemplate in Android and iOS Platform but working fine in the windows platform. It can be improved by using marker virtualization concept. But currently, the SfMaps control doesn’t have support to virtualize markers while providing larger number of markers on zooming and panning. So, we have logged a feature request for this requirement, and it can be tracked through our feedback portal below.


Please cast your vote to make it count. We will prioritize the features every release based on the demands, and we don’t have an immediate plan to implement this feature and it will be included in any of our upcoming releases.

If you have any more specifications/suggestions to the feature-request, you can add it as a comment in the portal.
