Struggling with slow loading times for ASP.NET MVC views using client-side rendering
I'm sure I'm missing something obvious here, but I keep running into I'm working through a tutorial and I've been struggling with this for a few days now and could really use some help. Building an application that heavily relies on ASP.NET MVC for the backend, I've noticed that the initial loading times for certain views are significantly affecting user experience. Specifically, views that include a substantial amount of data are taking too long to render on the client side when processed through AJAX requests. After profiling the application with built-in tools, I found that the server response is relatively quick, but the client-side rendering seems sluggish. I’ve tried optimizing the data returned from my controller by implementing pagination and filtering directly in the API response, which did help somewhat. Here's a snippet of the controller method: ```csharp public JsonResult GetItems(int pageNumber, int pageSize) { var items = _context.Items.Skip((pageNumber - 1) * pageSize).Take(pageSize).ToList(); return Json(items, JsonRequestBehavior.AllowGet); } ``` On the front-end, I’m using jQuery to make AJAX calls to fetch the data, and then I’m rendering it dynamically. Below is the AJAX call that retrieves the data: ```javascript $.ajax({ url: '/Items/GetItems', method: 'GET', data: { pageNumber: currentPage, pageSize: 10 }, success: function(data) { renderItems(data); }, error: function(xhr, status, error) { console.error('Error fetching items:', error); } }); ``` The `renderItems` function is responsible for creating the DOM elements and appending them to the view. Even after ensuring that I'm only manipulating the DOM for the new elements being added, the overall rendering feels laggy, especially when there are many items to display. I've also considered implementing a virtual scrolling strategy to enhance performance, but I'm uncertain about the best libraries or methods to use in conjunction with ASP.NET MVC. Are there specific techniques, libraries, or patterns that could improve the load times for client-side rendering in this context? Any insights or recommendations would be greatly appreciated! What's the best practice here? Is there a simpler solution I'm overlooking? This is happening in both development and production on Debian. Any feedback is welcome!
