How best to deal with large feature layers

I'm currently working on getting data from a massive trail feature layer to map on an iOS app. In order to display the individual trails in different colors I thought to use the #iOS SDK filter functions to filter the data for each trails and display the filtered trail data as a different feature layer. The trail layer is massive so I see that this is taking the iOS app a sec to display the data. How do I do this filtering work remotely? Can I create new feature layers on arcgis from other layers remotely? Can this be done on a #ASP.NET Core webapp? Also generally what's the best way to deal with large data sets on mobile apps.
