I have an application that I've built that uses feature layers to pull in information and allow things such as only showing locations within a selected layer that has X property and/or Y attribute or locations within a certain radius.
There are 15 feature layers that get made on start up, so the load time is heavy and it hits the server pretty hard. If around 10 people are using the application at once it slows things down considerably. I was looking into doing identifytask, but I'm worried that I won't be able to do the search functionality (which is the largest portion of this application) if I eliminate the feature layers.
Is there a way to accomplish what I'm doing without feature layers?
