Four Seconds Max

This is an excellent article discussing the speed of web pages: (dead link 2015)

A couple of bullet points from the article:

  • The consequences for an online retailer whose site underperforms include diminished goodwill, negative brand perception, and, most important, significant loss in overall sales.
  • Online shopper loyalty is contingent upon quick page loading, especially for high-spending shoppers and those with greater tenure.
  • JupiterResearch recommends that retailers make every effort to keep page rendering to no longer than four seconds.


Also, Jakob Nielsen has two good articles on the same topic:

Those reference research dating from the 1960s' - 10 seconds is about the max you want to go.

Interesting stuff.
