    [CLOSED] Ext Controls rendering takes much longer time than expected

    Hello,

    The server side processing of the aspx files container ext.net component is taking much longer time than expected.
    i.e. the conversion from server tags e.g. ext:panel to div which happens on server during every request of .aspx pages . Is there any way that we can increase this speed ?
    Note: If a page contains only asp.net components it renders so fast in half the time compared to a page with ext components.

    Hello!

    Well, ExtJS components themselves takes more time to render as they are much complex and javascript-demanding resources.

    Are you saying that the time from beginning to load the page until the page is actually displayed to the user (after JavaScript also processed), or did you specifically instrument in the code behind part of the execution?

    Some days ago I've instrumented our examples explorer, and code behind time was by far, much far, behind the time for actual JavaScript to process and build a page full of controls.

    Do you think you can write a test case showing this behavior and share with us, so we can provide a more accurate feedback?

    As for improving performance, there's no general rules. For example, for a gridPanel, you can use remote loading, remote paging, infinite-buffered scrolling. For tabs you can load them as they are shown, windows and panels likewise...

    I believe plain ASP.NET components uses much simpler if not native HTML/HTML5 components, that is inherently faster, but I doubt they can do as much as Ext.NET's set of components (which are essentially ExtJS 5 components plus an extra set of specific and helpful components).

    Controls rendering takes long time

    Dear Team


    The delay what we point out is "the conversion of .aspx to html". When the user opens the page test.aspx page in a browser there are 2 major process


    Stage 1 - Server Side Process
    "the request hits the server and all the ext.net controls in that page are processed by its handler and returned to client / browser as an html".


    Stage 2 - Client Side Process
    "the client receives the html/js/css and process it and displays on browser"


    We are concerned about Stage 1. This take more time than Stage 2.
    We believe Ext Handler is responsible for this conversion and we are curious to know is there something we can do about it to make it faster?


    Thanks..
