When I first started my work on web performance back in 2004, I came across Christine and Lori's article about this experiment. I found it fascinating, even though it contradicts what I evangelize. Here's the important takeaway: It's not all about speed, and it's not all about design. Both of these areas, along with others (uptime, bugs, security), affect user perception. The challenge for web developers is to figure out where to focus right now. That's why I created YSlow - so web devs could easily see if they had performance issues. It's harder to quantify this when it comes to design. We know that speed affects users, as evidenced by the many studies presented at the Velocity conference. Trying to determine which factor is most important for a web site is like asking what's the most important repair to your house - it all depends on the current state and which areas are strong and which need more shoring up. Keeping all other things constant, it's been shown that making a web site faster improves user metrics. It would be fascinating to hold performance constant, and see how changing the design affects user metrics. I'm sure user metrics would improve, but by how much, and how could we trade that off against possible performance improvements.

Very interesting podcast. Like anything though I think there is a balance between focusing on useability and download time. I see many sites that have really long download times because the images have not been compressed properly to a manageable size. Also, I think people tend to focus on download time because that is an easily measurable metric. Useability, as important as it is, is difficult to properly quantify. So ... are there any tools that would help me mimic how people experience my glass art jewelry site (lots of images) on a 56k modem? Also, I'd like to see the order in which my content downloads. Any tool for that?

Complete page load times is not the same as the time to start showing something useful to the user. The incremental loading of items - including secondary menu graphics and lots of items below the fold, or high res graphics loading after all the text has been loaded, change the perceptions of how fast a page loads. This is where a good designer along with a good technical programmer of web pages can fool the person into thinking a page is faster than what is is by just giving the user something to start scanning (and if they are really interested reading) on the page. When everyone was using dyamically sizing tables to layout pages with unsized graphics that was the worse - eveything had to come down before anything was seen due to the way tables are designed to be rendered by the browser. Most sites now-a-days will ensure that text is rendered (delivered) first with graphics coming down last into a predefined sized zone with defined placement so the browser does not have to figure out where to put it on the fly - but is told where to put it and thus save time. Course not all rules are to be followed - I have some hugh photos on my site so page load is going to be slow - but the people want to see the photos (else the words have no context when comparing aircraft, parts of castles, flowers, people etc) so you ensure that by the time they can read the text the graphics are there.

Alexander brought up the point that I was wondering. I've seen a number of sites that get slowed up because they are downloading banner ads and the like first, which can greatly lengthen the amount of time it takes for the actual content to show up. I see those sites as slow, but would be curious to see the time differences with those sites and sites as I judge as normal or fast loading.

Alexander, great question. We don't have to ask the interns to re-watch the video because they got those numbers already on the first pass. (I just didn't mention it in the podcast.) Turns out loaded in a single burst, coming in on average at 8 seconds per page. Amazon, as you suspected, loaded incrementally, with the first page full loading long before the 34 seconds it took to load the average page. But here's the kicker: the first screenful on Amazon took 11 seconds to load. It was still 3 seconds slower than the entire page for Yet, users consistently rated Amazon to be much faster than

Measuring the time that the Netscape logo throbs may be misleading if a page is presenting you interesting content even though it has not completely downloaded. I wonder: if the interns went back through the hours of video (ha ha!) to time how long it took for some meaningful content to appear on the page... (rather than how long the Netscape logo spun). Do you think it would show any differences?

[...] Users rate some sites consistently slow and other sites consistently fast. For example, is rated slow. But when looking at the data, the sites that were rated slow weren’t all really slow. Amazon is rated as fast, and it isn’t really that fast (fast enough, but not crazy fast). So why do users feel some sites are slow or fast? ( loaded faster than in the test, yet was perceived as very slow.) [...]
