Learn how to speed up Internet Explorer 8 by increasing the connections limit in Windows Vista and XP.
When a web browser (IE 8 or Firefox for example) connects to a website it establishes connections. Each connection downloads one thing whether it is the html of the page, an image, or ad. Connections are used as a throttle that’s being held back to keep web servers and the internet from getting overloaded.
By default IE 8 only establishes six simultaneous connections at a time to download a web page. The six simultaneous connections limit is specified in the HTTP standard. The six connections limit can be changed on your computer through a registry edit.
Increasing the maximum allowed simultaneous connects from 6 to 16 can increase the speed of some web sites because the sites are downloaded in larger chunks at a time. Keep in mind that this won’t work on all web sites because the number of connections limit can be controlled by the web server.
Don’t expect this hack to make IE 8’s download speed super fast, but it will make some more advanced web sites more responsive.
