Download Times*

Connection Rate Download Time

28.8K 156.02 seconds
33.6K 134.02 seconds
56K 81.21 seconds
ISDN 128K 26.26 seconds
T1 1.44Mbps 4.11 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 10 total objects for this page, that computes to a total lag time due to latency of 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 1 which most browsers can multithread. Minimizing HTTP requests is key for web site optimization.
  • TOTAL_OBJECTS - Caution. You have 10 total objects on this page. Consider reducing, eliminating, and combining external objects (graphics, CSS, JavaScript) to reduce the total number of objects, and thus separate HTTP requests.
  • TOTAL_IMAGES - Caution. You have a moderate amount of images on this page (6 ). Consider using fewer images on the site or try reusing the same image in multiple pages to take advantage of caching.
  • TOTAL_MULTIM - Congratulations, the total number of external multimedia files on this page is 1 .
  • TOTAL_SIZE - Warning! The total size of this page is 397456 bytes, which will load in 81.21 seconds on a 56Kbps modem. Consider reducing total page size to less than 30K to achieve sub eight second response times on 56K connections. Pages over 100K exceed most attention thresholds at 56Kbps, even with feedback. Consider 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, or even embedding them into high-traffic pages.
  • HTML_SIZE - Congratulations, the total size of this HTML file is 7393 bytes, which less than 20K. Assuming that you specify the HEIGHT and WIDTH of your images, this size allows your page to display content in well under 8 seconds, the average time users are willing to wait for a page to display without feedback.
  • IMAGES_SIZE - Warning! The total size of your images is 376441 bytes, which is over 30K. Consider optimizing your images for size, combining them, and replacing graphic rollovers with CSS.
  • SCRIPT_SIZE - Warning! The total size of external your scripts is 8362 bytes, which is over 8K. Consider optimizing your scripts for size, combining them, and using compression where appropriate for any scripts placed in the HEAD of your documents.
  • MULTIM_SIZE - Caution. The total size of your external multimedia files is 5260 bytes, which is between 4K and 20K. 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.
