Speed

Speed continues to be really underestimated. Little known fact: Amazon internal testing showed that 100ms extra pageload time means 1% less sales. Google tests show that 500ms longer pageload (half a second) means 20% less traffic.

Meditate on those numbers for a moment, and then tell me your webteam takes speed seriously enough.

    Any chance of a real source / reference for those numbers? Otherwise people will just say it’s hearsay and rumour. :-(

    I knew about the Google stats on this one but not about the Amazon one. Matter of fact, is I couldn’t find the place where this is stated. Do you have any pointers?
