User load

The user load on a system can drastically affect its hardware requirements. The more users, the more resources are needed. It is not only the number of users that can affect system performance, but the way they use the system. Generally speaking, users can be divided into two groups: Power Users and Typical Users.

User profile overrides

This option simply allows administrators to disable wallpaper that is associated with a user's profile. Some users may have graphically intensive wallpaper associated with their mandatory or roaming profile. Disabling wallpaper could provide these users with better performance over slow network connections.
