Download Times*
| Connection Rate | Download Time |
|---|---|
| 14.4K | 1.28 seconds |
| 28.8K | 0.84 seconds |
| 33.6K | 0.78 seconds |
| 56K | 0.63 seconds |
| ISDN 128K | 0.47 seconds |
| T1 1.44Mbps | 0.41 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 2 total objects for this page, that computes to a total lag time due to latency of 0.4 seconds. Note also that this download time calculation does not take into account delays due to XHTML parsing and rendering.

# 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 - Congratulations, the total objects on this page (including the HTML) is 2 which most browsers can multithread in a reasonable amount of time. Minimizing HTTP requests is key to minimizing object overhead (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.
- TOTAL_SIZE - Congratulations, the total size of this page is 1132 bytes. This page should load in 0.63 seconds on a 56Kbps modem. Based on current average web page size and composition trends you want your page to load in less than 20 seconds on a 56Kbps connection, with progressive feedback. Ideally you want your page to load in 3 to 4 seconds on a broadband connection, and 8 to 12 seconds for the HTML on a dialup connection. Of course, there's always room for improvement.
- TOTAL_SCRIPT - Congratulations, the total number of external script files on this page is 1 . 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 1132 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.
- MULTIM_SIZE - Congratulations, the total size of all your external multimedia files is 0 bytes, which is less than 10K.
