*Note that these download times are based on the full connection rate for ISDN and T1 connections. Modem connections (56Kbps or less) are corrected by a packet loss factor of 0.7. All download times include delays due to round-trip latency with an average of 0.2 seconds per object. With 26 total objects for this page, that computes to a total lag time due to latency of 5.2 seconds. Note also that this download time calculation does not take into account delays due to XHTML parsing and rendering.

# Congratulations. This site is using HTTP compression, otherwise called content encoding using gzip. The sizes reported here are for compressed content sent from the server to the client.

* CSS alternate stylesheets may be referenced in the HTML but are not actually downloaded until they are needed and are therefore not included in the total page size.

Analysis and Recommendations

  • TOTAL_HTML - Congratulations, the total number of HTML files on this page (including the main HTML file) is 2 which most browsers can multithread. Minimizing HTTP requests is key for web site optimization. Y
  • TOTAL_OBJECTS - Warning! The total number of objects on this page is 26 which by their number will dominate web page delay. Consider reducing this to a more reasonable number. Above 20 objects per page the overhead from dealing with the actual objects (description time and wait time) accounts for more than 80% of whole page latency. See Figure II-3: Relative distribution of latency components showing that object overhead dominates web page latency in Website Optimization Secrets for more details on how object overhead dominates web page latency. Combine, refine, and optimize your external objects. Replace graphic rollovers with CSS rollovers to speed display and minimize HTTP requests. Consider using CSS sprites to help consolidate decorative images. Using CSS techniques such as colored backgrounds, borders, or spacing instead of graphic techniques can reduce HTTP requests. Replace graphic text headers with CSS text headers to further reduce HTTP requests. Finally, consider optimizing parallel downloads by using different hostnames or a CDN to reduce object overhead.
  • TOTAL_IMAGES - Caution. You have a moderate amount of images on this page (14 ). 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 - Caution. The total number of external CSS files on this page is 4 , consider reducing this to a more reasonable number. 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 upon subsequent requests, CSS files slow down the initial display of your page. Combine, refine, and optimize your external CSS files. Ideally you should have one (or even embed CSS for high-traffic pages) on your pages. You can optimize CSS files using shorthand properties, grouping, and then minify and GZIP compress them to reduce their footprint. Remember to place CSS files in the HEAD and JavaScript files at the end of the BODY to enable progressive display.
  • TOTAL_MULTIM - Congratulations, the total number of external multimedia files on this page is 1 .
  • TOTAL_SIZE - Caution. The total size of this page is 145169 bytes, which will load in over 20 seconds on a 56Kbps modem - or 34.10 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 - Caution. The total number of external script files on this page is 5 , consider reducing this to one or two. Combine, refactor, and minify to optimize your JavaScript files. Ideally you should have one (or even embed scripts for high-traffic pages) on your pages. Consider suturing JavaScript files together at the server to minimize HTTP requests. 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 13262 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 - Congratulations, the total size of all your images is 42029 bytes, which is less than 50K. Even with a 50K HTML page this page should load in less than 20 seconds on a 56Kbps connection. Ideally each image should be less than 1160 bytes, to easily fit into one TCP-IP packet.
  • SCRIPT_SIZE - Warning! The total size of external your scripts is 38186 bytes, which is over 20K. Consider optimizing your JavaScript for size, combining them, and using HTTP compression where appropriate for any scripts placed in the HEAD of your documents. You can substitute CSS menus for JavaScript-based menus to minimize or even eliminate the use of JavaScript.
  • CSS_SIZE - Warning! The total size of your external CSS is 41388 bytes, which is over 20K. Consider optimizing your CSS for size by eliminating whitespace, using shorthand notation, and combining multiple CSS files where appropriate. By using labeled container cells and descendant selectors you can target chunks of HTML content efficiently without the need to embed extra claases and styles.
  • MULTIM_SIZE - Caution. The total size of your external multimedia files is 10347 bytes, which is between 10K and 30K. Consider optimizing your multimedia and eliminating features to reduce this to a more reasonable size. Or, consider a vector-based format such as Flash or SVG.
