IE 9 and SharePoint are using too much of memory

The problem is associated with an IE addon NameCtrl Class which is a part of SharePoint that handles presence information.

You can work around this issue either by disabling just this addon in IE or by turning off presence information at the SharePoint site level.


To do this go to
1. Central Administration
2. Application Management
3. Manage Web Applications
4. Select your site
5. General Settings
6. Enable additional actions and Online Status for members -> No
