Group Policy and Internet Explorer 8
There are approximately 1300 Group Policies for managing Windows(R) Internet Explorer(R) 8. Configuring these for the first time may seem like a daunting task. This section provides recommendations for the following important areas: security, performance, and compatibility with Internet Explorer 7 and Internet Explorer 6. This section also lists all the new Group Policies added in Internet Explorer 8. The Group Policies are listed with information on the policy setting name, scope, and policy path. The policy setting name gives a short description of what the policy does. For more information about each policy, see the policy explain text provided in the Group Policy editor. Group Policies can be set in either Machine or User scope. Machine policy takes precedence over user policy. Finally, the policy path is where the policy is located under the Administrative Templates in the Group Policy editor.
The following table lists the new Group Policies in Internet Explorer 8.

Internet Explorer 8 has been designed with performance in mind. Certain Group Policies can be used to help improve performance within your environment. As performance is affected by factors like bandwidth availability, specific sites, and network infrastructure, this section only lists Group Policies that an IT professional may wish to investigate.
The Add-ons and Third-Party Browser Extensions are typically provided by third parties, and may not share the same performance goals as Internet Explorer. Add-ons and browser extensions are known to have the potential for significant performance impact. The following Group Policies can be used to manage add-ons and browser extensions in your environment:

Set tab process growth
In Internet Explorer 8, the default connection limit has been increased from two connections per host to six connections per host. Connection scaling ma however, there are several factors involved, including bandwidth availability, specific sites, and network infrastructure. Depending on your environment, connection scaling settings may improve performance.
The Set tab process growth Group Policy allows you to set the rate at which Internet Explorer creates new tab processes. There are two algorithms Internet Explorer uses. The default algorithm has four settings: low, medium, high, or default. Low creates ve medium creates a moderate num and high allows the tab process to grow very quickly, and is intended only for machines with ample physical memory. The default setting creates the optimal number of tab processes, based on the operating system and amount of physical memory. In most circumstances, default is recommended. However, if the systems on your environment do not have ample memory, setting the tab process growth to low may improve performance.
The second algorithm for Set tab process growth Group Policy sets an explicit integer number of tabs per process. On Terminal Server, the default value is the integer “1”.
