Why is my mobile GIS app so SLOW?
May 4, 2016  by Matt Sheehan

I hear this question all the time: why is my mobile GIS app so SLOW? Whether simply loading a map, trying to edit features on the map, or routing; mobile GIS apps can be maddeningly slow. More than maddening, this slowness can actually get in the way of getting work done!

In this post we will discuss the cause and solutions to mobile GIS app slowness.

So what is the cause of mobile GIS app slowness?

For mobile GIS there are two primary causes:

1) Poor wireless connectivity – In both remote and populated areas wireless reception can be very variable. Take a look at the wireless signal bars on your smartphone or tablet. You will see changes in signal strength as you move. The weaker the signal the longer it will take for your mobile GIS app to load or return results. Sometimes you will wait and wait and the application fails. Very frustrating.

2) Loading a large number of features – If you are using a mobile GIS app which loads tens of thousand of features eg points representing water valves, your application will likely be impacted. Often that means a poor performing app. You are taxing the resources of your smartphone or tablet.

So two core reasons for mobile GIS app slowness: wireless connectivity and feature overload.
