is optimized for applications, but you can change it so that the processor is used more efficiently for background services by simply clicking the radio button You also see the Page File (Virtual Memory) Change button If you click Change, you see the Virtual Memory window, shown in Figure 10-14 Virtual memory allows Windows Vista to use a portion of the computer s hard disk as a memory storage area As data is loaded into memory and memory becomes low, pages of data are written to the hard disk and recalled as they are needed This feature allows Windows Vista to keep more frequently accessed information readily accessible in physical memory, even when physical memory begins to run low As you can see, Windows Vista is set to manage its own virtual memory settings, and it does a good job of this However, you can manually input minimum and maximum sizes for the page file, if you like The commonly recommended amount is 15 times the amount of physical RAM installed on the computer So, if you have 1GB of RAM, the recommended initial paging file size is 15GB

In addition to logs in Event Viewer, SQL Server logs information in different logs is accessible via Windows Explorer or SSMS

FIGURE 10-14

Another good piece of advice is to move the page file off of the drive that holds the system and boot partitions In this case, you need a second physical disk, but you tend to get better performance this way It is important to note here, however, that Windows Vista does a good job of managing its own memory settings, and as a general rule, you should allow Windows Vista to handle those settings on its own Incorrectly setting the virtual memory or choosing the No paging file setting option is likely to have adverse effects on system performance Also, providing more paging file room is not a replacement for physical RAM If the computer is running too slowly because there is not enough physical RAM installed on the system, then the paging file will not provide a cheap solution In short, the paging file is used to help Windows Vista s physical memory not replace it

When you install SQL Server, it creates a summarytxt file in the following directory:

Windows ReadyBoost is a new feature in Windows Vista that is designed to help speed up your computer Since ReadyBoost is a new feature, you re likely to see an exam question or two on this topic alone Fortunately, it is simple and straightforward, but you need to remember everything in this section to be ready for the exam

ProgramFiles\Microsoft SQL Server\90\Setup Bootstrap\LOG\

Windows ReadyBoost enables your computer to use removable storage space, such as USB flash drives, to speed up your computer Essentially, the USB flash drive works as additional flash memory for the system so that some data in memory can be written to the flash drive for use This frees up memory in RAM; however, it is not a replacement for the page file However, flash drives often contain both fast and slow flash memory, and Windows Vista can only use the fast flash memory to speed up the computer If you have a flash drive with a certain amount of storage space, but Windows Vista is only using a portion of it, then this is likely the reason Microsoft recommends that the amount of memory used for ReadyBoost be one to three times the amount of RAM installed in the computer For example, if your computer has 1GB of RAM and you use a 4GB flash drive, you can set aside 1GB to 3GB of RAM for ReadyBoost with the best performance In order to use ReadyBoost, simply plug your USB flash drive into a USB port on the computer The AutoPlay dialog box will appear and offer you the option to speed up your system using Windows ReadyBoost Simply select the option on the AutoPlay dialog box to use the feature If AutoPlay is not enabled, right-click the drive in Explorer and select Properties Then, go to the ReadyBoost tab and manually configure the settings
