Download Times*
| Connection Rate | Download Time |
|---|---|
| 14.4K | 461.84 seconds |
| 28.8K | 237.52 seconds |
| 33.6K | 205.47 seconds |
| 56K | 128.56 seconds |
| ISDN 128K | 48.53 seconds |
| T1 1.44Mbps | 16.27 seconds |
*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 66 total objects for this page, that computes to a total
lag time due to latency of 13.2 seconds. Note also that this download
time calculation does not take into account delays due to XHTML parsing
and rendering.
Page Objects
# This site is not using HTTP compression, otherwise called content
encoding using gzip. Consider compressing your textual content (XHTML,
JavaScript, etc.) with mod_gzip or similar products.
* 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 1 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 66 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, consideroptimizing parallel downloads by using different hostnames or a CDN to reduce object overhead.
- TOTAL_IMAGES - Warning! The total number of images on this page is 63 , consider reducing this to a more reasonable number. Recommend combining, replacing, and optimizing your graphics. Replace graphic rollover menus with CSS rollover menus to speed display and minimize HTTP requests. Consider using CSS sprites to help consolidate decorative images. Use CSS techniques such as colored backgrounds, borders, or spacing instead of graphic techniques to 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 to reduce object overhead.
- TOTAL_CSS - Congratulations, the total number of external CSS files on this page is 2 . 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 - Warning! The total size of this page is 578848 bytes, which will load in 128.56 seconds on a 56Kbps modem. Consider reducing total page size to less than 100K to achieve sub 20 second response times on 56K connections. Pages over 100K exceed most attention thresholds at 56Kbps, even with feedback. Consider optimizing your site with Website Optimization Secrets, Speed Up Your Site or contacting us about our optimization services.
- HTML_SIZE - Caution. The total size of this HTML file is 71564 bytes, which is above 50K but below 100K. With 50K of images and multimedia this means that your page will load in about 20 seconds. Consider optimizing your HTML and eliminating unnecessary features. To give your users feedback, consider layering your page or using positioning to display useful content within the first two seconds.
- IMAGES_SIZE - Warning! The total size of your images is 500958 bytes, which is over 100K. Consider switch graphic formats to achive smaller file sizes (from JPEG to PNG for example). Finally, substitute CSS techniques for graphics techniques to create colored borders, backgrounds, and spacing.
- CSS_SIZE - Congratulations, the total size of your external CSS is 6326 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.
