Hello John, I have a question regarding DNN pages and Pageblaster optimizing them. Firrst a quote from: http://developer.yahoo.com/performance/rules.html Front-end engineers that care about performance want a page to load progressively; that is, we want the browser to display whatever content it has as soon as possible. This is especially important for pages with a lot of content and for users on slower Internet connections. The importance of giving users visual feedback, such as progress indicators, has been well researched and documented. In our case the HTML page is the progress indicator! When the browser loads the page progressively the header, the navigation bar, the logo at the top, etc. all serve as visual feedback for the user who is waiting for the page. This improves the overall user experience. The problem with putting stylesheets near the bottom of the document is that it prohibits progressive rendering in many browsers, including Internet Explorer. These browsers block rendering to avoid having to redraw elements of the page if their styles change. The user is stuck viewing a blank white page. The problem caused by scripts is that they block parallel downloads. The HTTP/1.1 specification suggests that browsers download no more than two components in parallel per hostname. If you serve your images from multiple hostnames, you can get more than two downloads to occur in parallel. While a script is downloading, however, the browser won't start any other downloads, even on different hostnames.
END QUOTE My experience with my DNN website is that there is a white page for a long time and then all of a sudden the whole page is there. Even after installing and using Pageblaster it remains like this. This can be noticed especially when using a slow connection.
Until now I just used the default settings and did not work yet on the Static File Handler. I know some gain can be made with that. But it remains strange to me that DNN behaves like this. What else can be done so the page loads more progressively besides tweaking the page with the Static File Handler? Regards, Paco |
