This video looks at different performance options that can be configured in Windows7. This includes memory options, processor scheduling and Windows experience index.

Memory
The memory in your computer will determine how much software you can run at the same time. If your system starts running out of memory, the hard disk will start to be used as virtual memory. When this occurs, the performance of the whole system will be reduced. Since memory is stored in blocks called pages, the process of moving pages from memory to the hard disk and vice versa is often referred to as paging.
General performance troubleshooting
When troubleshooting problems in Windows 7, consider if the problem is an ongoing issue or just a spike. If the CPU for example suddenly goes to 100% and then drops just as fast, it usually does not mean that the CPU needs to upgraded.
Virtual memory settings
To change the virtual memory settings, open the control panel, select system and security and then select system. From here select the option, advanced system settings, and then the advanced tab. On the advanced tab press the button, change, to access the virtual memory setting.
Windows 7 will automatically manage the virtual memory settings for you. If you deselect the option, automatically manage paging file size for all drives, you can choose your own settings. If you have a hard disk that is dedicated to paging, you can select it here.
In the virtual memory settings you can set the size of the page file. When the initial size is set, the paging file will always be this size and will expand to the maximize size if required. Some administrators will set the initial size and the maximize size to the same size to prevent the page file from becoming fragmented.
Processor scheduling
In the system setting, Windows 7 can be configured to performance adjusted for programs or background services. By default, client operating systems like Windows 7 will be set to programs. This means that interactive programs, that is, programs that you interact with via the desktop, will respond quickly. An example of this is when you switch between different applications in the task bar. The option, background services, means that services like the printer spooler will be given more priority, which may mean your desktop applications will be slower to respond but your background processes should respond quicker. This option is normally configured on Server operating systems.
Windows Experience Index
The Windows experience index is the lowest score from a number of tests that Windows performs on the system. The tests are on the CPU, hard disk, memory and 3d graphics. The score determines what kind of effects Windows will use in the system. A low 3d score will mean effects like the Aero interface may be disabled. The index can be accessed in the control panel under system security and then the option, check Windows experience index.
