Ho scansionato il sito con analyze.websiteoptimization e mi dato questi dati.
Qlcuno mi puo aiutare a capirci qlcosa?
* TOTAL_HTML - Congratulations, the total number of HTML files on this page (including the main HTML file) is 1 which most browsers can multithread. Minimizing HTTP requests is key for web site optimization. Y
* TOTAL_OBJECTS - Caution. You have 19 total objects on this page. From 12 to 20 objects per page, the latency due to object overhead makes up from 75% to 80% of the delay of the average web page. See Figure II-3: Relative distribution of latency components showing that object overhead dominates web page latency in Website Optimization Secrets for more details. Consider reducing, eliminating, and combining external objects (graphics, CSS, JavaScript, iFrames and XHTML) to reduce the total number of objects, and thus separate HTTP requests. Consider using CSS sprites to help consolidate decorative images.
* TOTAL_IMAGES - Caution. You have a moderate amount of images on this page (15 ). Consider using fewer images on the site or try reusing the same image in multiple pages to take advantage of caching. Using CSS techniques such as colored backgrounds, borders, or spacing instead of graphic techniques can help reduce HTTP requests.
* TOTAL_CSS - Congratulations, the total number of external CSS files on this page is 1 . Because external CSS files must be in the HEAD of your HTML document, they must load first before any BODY content displays. Although they are cached, CSS files slow down the initial display of your page. Remember to place CSS files in the HEAD and JavaScript files at the end of the BODY to enable progressive display.
* TOTAL_SIZE - Caution. The total size of this page is 106779 bytes, which will load in over 20 seconds on a 56Kbps modem - or 25.08 seconds on a 56Kbps modem. Consider reducing total page size to less than 100K to achieve sub 20 second response times on 56K connections. Be sure to provide feedback for pages over 100K by layering your design to display useful content within the first two seconds. Consider optimizing your site with Website Optimization Secrets, Speed Up Your Site or contacting us about our optimization services.
* TOTAL_SCRIPT - Congratulations, the total number of external script files on this page is 2 . External scripts are less reliably cached than CSS files so consider combining scripts into one to minimize HTTP requests, or even embedding them into high-traffic pages. Placing external JavaScript files at the bottom of your BODY, and CSS files in the HEAD enables progressive display in XHTML web pages.
* HTML_SIZE - Congratulations, the total size of this HTML file is 8495 bytes, which less than 50K. Assuming that you specify the HEIGHT and WIDTH of your images, this size allows your HTML to display content in under 10 seconds, the average time users are willing to wait for a page to display without feedback.
* IMAGES_SIZE - Caution. The total size of all your images is 76191 bytes, which exceeds 50K. Consider optimizing and creatively cropping your images, and combining them where appropriate. Even better, replace graphic text and form controls with styled text to eliminate unnecessary HTTP requests. Ideally each image should be less than 1160 bytes, to easily fit into one TCP-IP packet.
* SCRIPT_SIZE - Caution. The total size of your external scripts is 19129 bytes, which is above 8K and less than 20K. Consider optimizing your scripts and eliminating features to reduce this to a more reasonable size. You can substitute CSS menus for JavaScript-based menus to minimize or even eliminate the use of JavaScript.
* CSS_SIZE - Congratulations, the total size of your external CSS is 2964 bytes, which is less than 8K.
* MULTIM_SIZE - Congratulations, the total size of all your external multimedia files is 0 bytes, which is less than 10K.
