Need help understanging Firebug's Net tab statistics

Even though my question is very similar to this one, it's not a duplicate.

Firebug NET Tab screenshot

The images shows the stats from Firebug's NET tab, each request is taking a fraction of a second (all requests add up to 2.9 sec), yet the total time adds up to 6 seconds.

How do I figure out which request took the longest time, and where did the extra 3 seconds came from?

Requests are not necessarily in parallel. Most browsers only pull 2 concurrent resources per host. So if all six of your resources are on the same host, they could simply be blocking. Furthermore, if these resources are JavaScript or some other resources that may be parsed on load.

Also note that the total time is when the page load event fires, so this doesn't necessarily mean that is a white screen for six seconds.

Check out the YSlow guidelines for more details tips on performance. I also recommend Building Faster Websites if you're really interested in this subject.
