I ran the test on my site and it showed numerous yellow/red flag issues on my forum page. Since I really haven't done much at all in the way of modifications there, I decided to check the xenforo forum page. It has pretty much the same warnings. When I read them they sound bad, like issues which need to be fixed. I really don't have the technical skills to know what issues should be investigated, and what I can ignore.
Can anyone share if these issues should be a concern? The below is for the XF site. I do know that overall the site loads fast, and you have done a great job optimizing the software. In order for me to ensure my site is optimized, I need to understand what I can disregard. Alternatively, if someone knows of a better site for this information, that information would be helpful as well.

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 38 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 - Warning! The total number of images on this page is 31 , 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_SIZE - Caution. The total size of this page is 181621 bytes, which will load in over 20 seconds on a 56Kbps modem - or 43.80 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.
- HTML_SIZE - Congratulations, the total size of this HTML file is 12837 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 32600 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.
- CSS_SIZE - Warning! The total size of your external CSS is 23874 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 - Congratulations, the total size of all your external multimedia files is 0 bytes, which is less than 10K.
