Google Shares Insights On Accelerating Web Sites

Posted by samzenpus on from the hurry-it-up dept.

miller60 writes "The average web page takes 4.9 seconds to load and includes 320 KB of content, according to Google executive Urs Holzle. In his keynote at the O'Reilly Velocity conference on web performance, Holzle said that competition from Chrome has made Internet Explorer and Firefox faster. He also cited the potential for refinements to TCP, DNS, and SSL/TLS to make the web a much faster place, and cited compressing headers as a powerful performance booster. Holzle also noted that Google's ranking algorithm now includes a penalty for sites that load too slowly."

    Now if only every website didn't include 300kb of Javascript libraries that I had to download.

  2. Measuring speed from *where* exactly? by buro9 · · Score: 5, Interesting

    Where are the measuring *from*?

    I've moved a site from Linode New Jersey to Linode London, UK because the target audience are in London ( http://www.lfgss.com/ ).

    However in Google Webmaster Tools the page load time increased, suggesting that the measurements are being calculated from US datacentres, even though for the target audience the speed increased and page load time decreased.

    I would like to see Google use the geographic target preference and to have the nearest datacentre to the target be the one that performs the measurement... or better still to have both a local and remote datacentre perform every measurement and then find a weighted time between them that might reflect real-world usage.

    Otherwise if I'm being sent the message that I am being penalised for not hosting close to a Google datacentre from where the measurements are calculated, then I will end up moving there in spite of the fact that this isn't the right thing for my users.
