It seems that if I run this in a new tab, I always get ~4078ms. If I click Reload, I get ~2141ms. If I click Edit > Create, I get ~2094ms. This was all on IE7 but I see the same inconsistencies on IE8. Should I just always open a new tab to get the real numbers? Thanks, great work! Steve, how should I deal with inconsistency in results.

To see every HTTP request you have to use some sort of packet sniffer. @Paul: Cuzillion shows the load time for scripts, so you can see that within Cuzillion itself.

Also, I guess the tool is intended to be used with something like IBM's PageDetailer, or am I missing something that Cuzillion does that I'm not aware of?

Fiddler is another cross-browser tool. HTTPWatch has good charts in IE, but they're a little different (they show "blocked" time which is a great feature as long as you understand it). Be careful using Net Panel in Firebug (see http://developer.yahoo.com/yslow/netpanelpatch.html ). I use IBM Page Detailer:

YSlow seems like it already does a fairly good job in figuring out what my page elements are. I wouldn't imagine that it would be terribly difficult for it to use that data to populate Cuzillion. You could run a check against a database to see if that combination of page elements has already been tested. If it has, return those results; if not, run the test through Cuzillion.

Morgan: I'll include CSS background images as another type of resource to add. 2. Eric: I added a checkbox to stylesheets for "use @import". The other ideas are good, too, esp. the download pause. 3. Hi Bill! I like the run multiple times, but since the download times are fixed it might not reveal much. I hope soon to get the code up on Google Code so you can download it from there, but no promised date right now. I've been kicking around the idea of a "page visualizer" as you describe in your 3rd bullet. I'll add "save your example" soon that ties in with a Cuzillion blog category. That provides a way for someone to save a Cuzillion page and ask "Why does it do this?" or "Look what I discovered!". 8. Vishal: I like the API idea, but that might be further out. When I get it up on Google Code maybe you can add that. 9. Ben: Wow, that's an awesome idea. Rather than being reactive like YSlow and evaluating a page, be proactive and suggest how the resources _should_ be ordered. 10. Steele: Images don't block downloads, so the iframe and script are all loaded in parallel. You have to use the packet sniffer of choice to see the download times. If I had JS instrumentation in the page to do that I worry it'll affect the results. 1. Morgan: I’ll include CSS background images as another type of resource to add.

What a great tool! Just a few quick questions; With ie8, if a page contains an Image, and an Iframe which contains an external script, will the external script in the iframe be loaded parallel with the image or will the loading of the image block the loading of the script in the Iframe? Also, is there a way we can access these load time profiles so that we can see differences in load orders? Kudos! What a great tool! Just a few quick questions;
