Xamarin Mobile Sorting Performance C#

I can't seem to get Currently developing a hybrid mobile application using Xamarin.Forms for a project that analyzes large datasets... I need to implement a custom sorting algorithm in C# that will efficiently handle data on mobile devices, which often have limited resources compared to desktop environments. The algorithm must be optimized for both speed and memory usage to ensure a smooth user experience. I've experimented with a few different approaches, such as using LINQ for sorting, but performance benchmarks indicate that it doesn't scale well with larger datasets. Here’s a simplified version of what I tried: ```csharp var sortedData = dataList.OrderBy(item => item.SomeProperty).ToList(); ``` This worked for small sets, but once I reached over a few thousand records, the app became sluggish. I revisited the classic quicksort algorithm to implement a more efficient version suited for mobile. Here’s the implementation: ```csharp public List<T> QuickSort<T>(List<T> list) where T : IComparable<T> { if (list.Count <= 1) return list; var pivot = list[list.Count / 2]; var less = list.Where(x => x.CompareTo(pivot) < 0).ToList(); var equal = list.Where(x => x.CompareTo(pivot) == 0).ToList(); var greater = list.Where(x => x.CompareTo(pivot) > 0).ToList(); return QuickSort(less).Concat(equal).Concat(QuickSort(greater)).ToList(); } ``` I wrapped this in a service class to maintain separation of concerns, following best practices. However, during integration, I noticed some lag when dealing with datasets over 10,000 items, particularly on lower-end devices. For testing, I've been using an Android emulator with limited RAM and CPU power. Are there any techniques or design patterns you recommend to further optimize the sorting operation? Additionally, if anyone has experience with adapting algorithms for mobile performance, your insights would be invaluable. Any suggestions for profiling the performance of this implementation would also be appreciated. Thanks in advance!
