Tune Background Task Resource Consumption
Many applications use background tasks to provide a mechanism for handling low-priority tasks in a single-user environment. In the Terminal Services environment, the scheduler is generally optimized for interactive responsiveness of foreground tasks (more like Windows NT Workstation or Windows 2000 Professional than Windows NT or Windows 2000 Server), though under Windows 2000 Terminal Services the administrator can select this. Also, the demands of running many interactive sessions on a single server required some architectural changes to the kernel that resulted in a small system cache. This means that, when Terminal Services are enabled, one user's background task will compete for CPU cycles with another user's foreground tasks. When multiple users are running both foreground and background tasks, the CPU demands are much higher than when all users are running only foreground tasks. This situation typically arises when a Terminal Server is also being used as an applications server to host a client-server application such as Microsoft SQL Server™ or Microsoft Exchange, perhaps in a branch office environment. It is generally not a performance issue when the Terminal Server has only a few users attached, but could become an issue when the server is trying to serve many users. Microsoft recommends that Terminal Servers be dedicated to serving client applications, but customers sometimes wish to run the Terminal Server as a multi-purpose applications server. To maximize CPU availability for all users, application developers should create efficient background tasks that are not resource-intensive, or turn off background tasks when Terminal Services are running. In Windows 2000 Server, the administrator will be able to choose whether to give more priority to background or foreground processes even when Terminal Services are enabled. This allows more granular performance tuning by administrators for their particular network and applications configuration.
