sql-server entity-framework performance mobile csharp

I'm testing a new approach and I'm relatively new to this, so bear with me. Recently started working on a mobile application that requires seamless interactions with a SQL Server database. Given the potential connectivity issues in mobile environments, I'm keen on optimizing our queries to reduce data transfer and enhance performance. Our current setup involves using Entity Framework Core 5.0 with SQL Server 2019. The app frequently retrieves user profiles and related data, which often results in large payloads. To mitigate this, I attempted to simplify our queries by explicitly selecting only the necessary fields: ```csharp var userProfiles = await _context.UserProfiles .Where(u => u.IsActive) .Select(u => new { u.Id, u.Name, u.Email }) .ToListAsync(); ``` However, the performance gains have been minimal. Another approach I considered was implementing pagination, but I’m unsure how to effectively paginate the results while maintaining a user-friendly experience. ```sql SELECT TOP 10 * FROM UserProfiles WHERE IsActive = 1 ORDER BY Id OFFSET @Offset ROWS FETCH NEXT @PageSize ROWS ONLY; ``` This SQL command works, but I’m worried about the impact it may have on user experience if they have to wait for data to load. Furthermore, I've been looking into caching strategies to store frequently accessed data. Using in-memory caching seems viable, but I need to ensure it doesn't cause stale data issues. Does anyone have insights on implementing caching with SQL Server effectively, especially in a mobile context? Lastly, I've read about the use of stored procedures to encapsulate complex queries, which might reduce the overhead of sending multiple individual queries from the client. Would this be advisable for improving performance, or are there other best practices I should consider? Any advice or shared experiences would be greatly appreciated. I'm using Csharp stable in this project. Has anyone dealt with something similar? For context: I'm using Csharp on CentOS. Any help would be greatly appreciated! The project is a microservice built with Csharp.
