4 Seconds Loading Time Is Maximum For Websurfers

nieske writes "Of course we all want webpages to load as fast as possible, but now research has finally shown it: four seconds loading time is the maximum threshold for websurfers. Akamai and JupiterResearch have conducted a study among 1,000 online shoppers and have found, among other results, that one third of respondents have, at one point, left a shopping website because of the overall 'poor experience.' 75% of them do not intend ever to come back to this website again. Online shopper loyalty also increases as loading time of webpages decreases. Will this study finally show developers of shopping websites the importance of the performance of their websites?"

      Slashdot does not use AJAX, just some Javascript, for the new discussion system. In essence, the only thing it does is hide all posts until you click on its header to expand it. The posts are there anyway, loaded along with the rest of the page. That way, it uses about the bandwith of the nested option, while presenting it as a dynamic threaded view. If they used AJAX, it would (probably) send an asynchronous query to the Slashdot servers asking for precisely the post you try to open. That does not happen, I checked tcpdump myself.

      Agreed, also, I would say the old humorous adage of...

      Statistics show that 70% of statistics are wrong.

      I'd also think that this is more FUD, since of course people are going to say "I'll never return to that website because once it never loaded for me". Of course, if said website was Amazon.com, I'm going to go all in and say that they will most likely return and that they where just unhappy at the time.

      Also, what where the survey questions? Where they worded to direct people to answer in a certain way? For example, where they written like this...Would you visit a website again if you had recurring bad experience with it?. Most experts agree that 4 seconds and more is a long time for a website to load and contribute this to a bad user experience. Would you agree?.

      Finally, this is a bit of a moot point, but page load times are not always the fault of the web server. Case in point, my wireless router sucks (hey, I got it from best buy for like $20 after rebates, I'm not complaining) and it will often just drop the wireless signal. This makes it appear that when you try to access a website, when you where just accessing another website just fine, that the website takes a long time to load or more often than not, doesn't load at all, making you think there are issues with that site, when there is not.

      I'd rather point out the obvious when it comes to the Internet... people expect to find broken sites. It's just the way everyone has grown up with the 'net. Crappy designed sites with stale content and broken links, multiple browsers (IE(win), IE(Mac) , Netscape/Mozilla, Safari) on multiple systems (Mac, Unix/Linux, Windows), security issues, internet issues with their ISP, web servers that go down, etc, etc, etc. People know that the nature of the Internet is volatile. Sure, they'll get angry and might never return if your site is a small 'mom and pop' shop, but when it comes to the 'major' sites such as CNN, MSN, Amazon, eBay, etc; then they will most likely return, even if it takes more than 4-seconds (which it does on CNN and if I remember right, they use Akamai).

      Saying 4 second load time will make customers never return is slightly FUD (since it's subjective). Saying a customer won't return if they type their zip code into their address bar, and your site claims it's invalid (when it's not) will probably do the trick. That's something web developers can change. Load times isn't alway in their hands. But that's not to say they shouldn't review their code for efficiency in execution.

(Select all that apply.)" - 65% said good navigation, page load time was 8th of 13 with only 40%. "Typically, how long are you willing to wait for a single Web page to load before leaving the Web site? (Select one.)" - 21% said 3 - 4 seconds, however 30% were willing to give the page 5 - 6 seconds (broadband numbers) and another 38% were willing to wait more than 6 seconds.

  34. Re:AJAX completely lacks performance. by inKubus · · Score: 3, Interesting

    It's pretty easy:

    If you're application uses a lot of repeated screens and is really only a data-view and entry application, you should go AJAX. Because the slightly longer initial load time (to load ALL the interfacey stuff) is better than having to rerender the interface over HTML every time you change views.

    If it's a step by step wizard type thing, or informational (think wikipedia) just get on with it using syncronous web pages.

    Where AJAX fails is in the hands of inexperienced developers, where they won't allow the app to load almost everything before running. This is not always possible--something like google maps is a good example of this. You are going to have to load the maps as you go because there's too much data. However, google maps really relies on Images as data which is not the most efficient. They need to expand their client to render the maps itself from GIS info (obviously the satellite overlay will need to come from images).

    Also, it fails when there is a high latency connection. However, a lot can be learned from past interfaces: feedback! Flash a div on the screen letting the user know it's loading, apply visibility:hidden when it's done. As long as the user knows that it's actually DOING SOMETHING and not just sitting there, they will give it the benefit of the doubt and wait. Test the connection latency at startup and then let the user know what you know. If you tell them in advance that they might experience poor performance because of their current connection, they are more likely to tolerate it.

    Good interface design is a lot more than having it be fast. You have to keep the user informed of the current situation. It's not slowness that annoys people so much as not knowing what's going on. Early X windows had that problem for me also. Whereas in Windows when you click something the window immediately is created by GDI while the actual application loads, in X the appliation is started somewhere and then IT creates it's own window. So when you click on an Icon, it takes a few seconds of nothing (it seems) while we wait for the kernel to find on FS, allocate memory for and run the executable which does it's own init and then FINALLY pops up it's window. If you're running over a network connection, there's no disk noise to let you know anything is happening, so you are basically just sitting there wondering if you should click again. I don't know if it's still like this.

    Anyway, my point is that there are a lot of tricks you can use to prevent user annoyance because it goes a lot further than some arbitrary time length.

  35. Depends entirely on what... by Kjella · · Score: 2, Insightful

    If I go to the front page of an online newspaper or similar site, I expect it to take long to load. If I click an article link, my patience is very thin because my target is simple article text, possibly with an illustration. Same with an online store. Also, there's a few tricks that lets the browser render it before it's loaded all the items - for example setting an image's height and width attributes. Not everyone has learned that yet. Also it depends on how much meaningful content there's on a page. If I have to visit a [break] new [break] page [break] for [break] every [break] sentence, I'm a lot less patient than if you just load it in one big honking page that I can scroll.

    In short, measuring cost (time) without measuring benefit (content) is meaningless. If google's search page took four seconds to load, they'd be a dead duck. Other pages couldn't be rendered in four seconds with a Core 2 Quad and GigE, but are still highly successful. The pages you want to check is where the user asked you for something specific, in which case you'd better deliver ASAP without crapping up the page with everything he didn't ask for. Pages that are slow, I can live with. Pages that are slow, deliver little and waste time on meaningless stuff I don't.

  36. Notice who sponsors the study by melted · · Score: 2, Interesting

    Not to argue that nothing on the web should take more than 4 seconds to load (on _second_ load), but notice who sponsored the study - Akamai. It's like if Microsoft sponsored a study "proving" that Linux sucks.

    Caching is your friend. If you cache, don't forget to version your stuff as well:

    <script src="foo.js?d=md5sum-of-the-script"></script>

    And do this with everything you cache - css, xml, xsl, whatever.

  37. Answer to a survey vs. Real world action by The_Crowder · · Score: 2, Insightful

    The danger of conducting surveys is that the answer to a question often times varies from what a user will really do in the real world.

    Take the topic of "...the New Threshold for Acceptability..." as an example, the survey asks the question: "Typically, how long are you willing to wait for a single web page to load before leaving the site?" 31% of users said that they were willing to wait less than 5 seconds for a page to load before leaving. I am willing to bet that if you were to evaluate the metrics of online retailers you would find that the number of people leaving your site after a sub 5 second page load is less than 31%.

    On a similar note, this survey fails to tell us whether this is something a user is willing to put up with only once or on every page load. It is my suspicion that a one time page load of 5 - 6 seconds is not going to cause "A full one-third of online shoppers with a broadband connection..." to abandoned the page; however, I would be willing to accept that if every page took 5 seconds or more to load on a broadband connection you would see a large amount of users abandoning the site.

    Finally, I found it very interesting that the survey limited the answers to 6 possibilities (sub 1s, 1-2s, 3-4s, 5-6s, 6+). In my opinion, they made a big assumption in choosing 6s as the threshold of acceptability...where did that number come from/why was it chosen as the cap? I think the survey would have been able to benefit from having a higher range, perhaps to 10s as suggested by Jakob Nielsen (http://www.useit.com/papers/responsetime.html)
