Why is the initial map load time so long? Is there something I can optimize?

When a user selects a map in Geocortex Go to open the map quickly opens to a blank screen, then over the next few seconds some layers start drawing. It can then take up to 20 seconds for all of the layers to initialize, for lack of a better term. During this time neither the map layers list or legend work, they just show loading. Once everything is loaded the map and and tools are quick and work great, load times of layers is fast.

 

Is there a way to speed up that initial loading? It's a big complaint I get from users that every time they open the app fresh they have to wait a good 20 seconds to really use it.

  Hi Max,

   

  Depending on the device that you are loading and the amount of map data that is being pulled in, the initial load time can vary greatly. If you are using a large base map, you could consider sideloading a TPK.

   

  What devices are you seeing this on and what's the approximate amount of map data being loaded (number of layers, features, etc.)?

   

  Thanks, Stefan

  Hi Stefan,

   

  Our users are using it on their personal devices so it's a wide mix of iPhone and Android phones, the speed does obviously vary depending on the age and hardware of the phone I would fully expect that.

   

  We have several maps with a varying amount of layers in each, the simple maps do load faster for sure, but there is still a several second wait as everything initializes. A simple map has ten layers with not many features in each. The more complicated ones have a large tpk basemap with 16 layers, not all of which are turned on or visible at certain scales by default. Some of those layers have thousands of features though.

   

  I have been very impressed with performance on those maps considering how many layers and features there are for a phone, it's the just the initial load time that is pretty slow.

  Hi Max,

   

  Thanks for your feedback. I've added you name to the list of stakeholders who have noted this. We are currently looking in improvements around this.
