The increasing number of concurrent browser connections
While I was catching up on the development of IE8 I found this over at the IE blog: In IE8 Beta 1 we also increased our per-server connection limit from 2 to 6. What this means is that in IE7 and below pages could only download 2 elements from a given server at any one time. Increasing that limit to 6 allows sites to download 3 times as much content in parallel, which should translate into faster page download times when bandwidth is available....
