What is the performance of INNER JOIN vs WHERE?

ASP.NET Webform: inline code (<%= %> ) vs Server Control Performance?

  • Let's forget about state management, maintenance perspective, etc ... and focus on render performance only Which of render method has better performance ? <%= ... %> or Server Control (or  Html Server Control/ Custom Control/ UserControl) ? e.g 1: <a href='<%=ResolvedUrl("~/Page1.aspx")'>Page1</a> vs <asp:HyperLink ID="lnk1" runat="server" NavigateUrl="~/Page1.aspx" /> e.g 2: using <% %> with foreach to render a DataTable vs using DataGrid In my opinion, <% %> will win not only in these 2 examples but also in most cases. As in http://ASP.NET MVC, we use inline code in Views to render HTML. What's your opinion ?

  • Answer:

    I always recommend that people stop relying on http://ASP.NET Web Forms controls for simple non-form HTML elements like links, labels, text, etc. The performance is better and you'll have an easier time to convert to http://ASP.NET MVC in the future.

This is actually an apples-to-oranges comparison. Render-time-wise, Server Controls will always render slower than pure HTML with inline code, because of all the extra work involved in creating the Server Control, such as creating and maintaining the viewstate, executing the events chain, using filters etc. However, Server Controls has the advantage of functionality available in the server side, as opposed to pure HTML elements. In general, if you don't need the server side functionality of the Server Controls, don't use them. But if, however, you'll want to make your link visible or non-visible in your server side code, or would like the built-in sort functionality of the GridView - then use them.
