4 Seconds Load Time is all you have!
A 4-second load time is all you have to show something to your users.
Ref: Slashdot - Based on a recent retail research report, if your web site doesn't load in 4 seconds or less, your visitors will leave before they even get to the site.
For most techno-geeks, 4 seconds isn't long, but everyone wants fast-loading web pages regardless of what is on your site.
Keep in mind that the survey is focused towards 1,058 retail online shoppers, not bloggers or personal pages.
So if you are running your own online retail business, make sure your graphics are optimized, you're using CSS instead of tables, and using short quality content for your shoppers.
