.NET Forum / ASP.NET / General / April 2008Slow loading time. Extension 3.5
I have been experimenting with VWD Express Extension 3.5 and noticed that quite often it takes up to 1..2 min to load external js or css files. This occurs often after rebuilding the site. The problem seems to be linked to retrieving small ( approx 200 bytes) graphics files, as evidenced in Firefox' Firebug tracing graphics. Currently, the script manager is included in the master page, the external js file in the header section, and the page theme referenced in the config file. Is this the right approach or does Ext 3.5 have some bugs? With ASP.NET 2.0 load-up time was satisfactory. I tried deleting the external js file to no avail. How can I speed up loading time? TIA for sharing any thoughts. Are you just dealing with initial load time? If so, you may or may not be able to alleviate the situation and should attempt to run the JITTer when you deploy through the precompile.axd file. More and more of the code is being compiled when you compile a web project. Could there be a bug in 3.5 Extensions? Certainly. It is still in beta. I would log your findings, along with code, and a step by step description of what you did. The place to log is one Connect. You can also get to the team via the forums on www.asp.net. In addition, if you want someone to figure out what is wrong with your code, or if it is a bug, you should post code here, as well. The more info, the easier it is for other people to help you.

Gregory, thanks for your feedback. I'll follow your suggestions and post my findings in the fori you specified. Meanwhile, here is a small snippet taken from the master page (aside from the ScriptManager tag, this is identical to the ASP.NET 2.0 script which works fine): .... <head runat="server"> <meta http-equiv="Content-Type" content="text/html;charset=utf-8"/ <script type="text/javascript" src="/AndersShop/Includes/ JavaScript/Common.js"></script> <title id="PageTitle" runat="server"></title> </head> <body > <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" EnableStateHash="False" EnableHistory="True" OnNavigate="ScriptManager1_Navigate" /> <div id="page" > .... The config includes the css theme reference: <pages styleSheetTheme="Theme1"> Has anyone else been having this. Everything was going fine - VS2005 asp net2. Last night I installed 3.5 because I wanted to use the TimeZoneInfo class. Added a reference to System.Core. Went and added TimeZoneInfo classes all over the place. Straight away load times went up to from < 1 sec to > 20 sec. Can't remember doing anything else that could have an impact. Removed the references and classes - still long load times... I might uninstall 3,5 and see what happens there. Any ideas much appreciated, Cheers, Mike. > I might uninstall 3,5 and see what happens there. All sorts of trouble apparently. I wish I'd found http://blogs.msdn.com/astebner/articles/492809.aspx before I started getting silly. Anyway, removed the 3.5 references and all is back to good. Application initial load is extremely slow. I am not sure if this is to do with something running on the machine. It was fine earlier today after I recompiled. It is definitely flaky... Kind of scares me because we have invested enough into 3.5 upgrade. Some of the things I am planning is run a 1) aspnet_compiler.exe before we start browsing the site.. 2) use the MSbuild with other options (do not know what as of now -:)) Any one able to find any solution on this? thanks -Kumar make sure u turn off indexing service on the folder. > Application initial load is extremely slow.
