How To Manual steps to set performance options in Windows XP

Manual steps to set performance options in Windows XP

How to manually manage processor time Windows manages system processing. Windows can allocate tasks between processors and manage multiple processes on a single processor. However, you can set Windows to allocate more processor time to the program that you are currently running. The added processor time causes programs to respond more quickly. Or, if you have background programs such as printing or disk backup that you want to run while you work, you can have Windows share processor resources equally between background and foreground programs. Note You must be logged on as an administrator to the local computer or have the correct network credentials to make certain changes in System.

How to manually change the performance of foreground and background programs

1. Click Start, click Run, and then type sysdm.cpl in the Open box.
2. Click the Advanced tab, and then click Settings under Performance.
3. Click the Advanced tab, and then use one of the following methods under Processor scheduling:
• Click Programs to assign more processor resources to the foreground program than the background program.
• Click Background services to assign equal amounts of processor resources to all programs.

Notes
• If you click Programs, the foreground program runs more smoothly and responds more quickly. If you want a background task such as a Backup utility to run faster, click Background services.
• The Programs option allocates short, variable time slices (quanta) to running programs, and the Background services option assigns long, fixed quanta.

How to manually manage computer memory

When your computer is running low on RAM, and you must have more RAM immediately, Windows uses hard disk space to simulate RAM. This is known as virtual memory. It is also known as the paging file. This is similar to the UNIX swapfile. By default, the virtual memory paging file (named pagefile.sys) that is created during installation is 1.5 times the RAM on your computer. You can optimize virtual memory use by dividing the space between multiple drives and by removing space from slow or heavily accessed drives. To best optimize your virtual memory space, divide it among as many physical hard drives as possible. When you select drives, follow these guidelines:

• Try to avoid having a paging file on the same drive as the system files.
• Avoid putting a paging file on a fault-tolerant drive such as a mirrored volume or a RAID-5 volume. Paging files do not require fault-tolerance, and some fault-tolerant computers experience slow data writes because they write data to multiple locations.
• Do not put multiple paging files on different partitions on the same physical disk drive.

How to manually change the size of the virtual memory paging file

You must be logged on as an administrator or as a member of the Administrators group to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.

1. Click Start, click Run, and then type sysdm.cpl in the Open box.
2. Click the Advanced tab, and then click Settings under Performance.
3. Click the Advanced tab, and then click Change under Virtual memory.
4. Under Drive [Volume Label], click the drive that contains the paging file that you want to change.
5. Under Paging file size for selected drive, click Custom size, type a new paging file size in megabytes (MB) in the Initial size (MB) or Maximum size (MB) box, and then click Set.If you decrease the size of either the initial or maximum paging file settings, you must restart your computer to see the effects of those changes. When you increase the paging file size, you typically do not have to restart your computer.

Notes
• To have Windows select the best paging file size, click System managed size. The recommended minimum size is equivalent to 1.5 times the RAM on your computer, and 3 times that figure for the maximum size. For example, if you have 256 MB of RAM, the minimum size is 384 MB, and the maximum size is 1152 MB.
• For best performance, do not set the initial size to less than the minimum recommended size under Total paging file size for all drives. The recommended size is equivalent to 1.5 times the RAM on your computer. It is good practice to leave the paging file at its recommended size. However, you may increase its size if you frequently use programs that use much memory.
• To delete a paging file, set both the initial size and the maximum size to zero, or click No paging file. We strongly recommend that you do not disable or delete the paging file.

How to manually optimize the memory usage

You can optimize your computer's memory usage. If you use your computer primarily as a workstation instead of as a server, you can devote more memory to your programs. Your programs will work faster and your system cache size will remain the default size that came with Windows XP. You can also set aside more computer memory for a larger system cache if your computer is used primarily as a server, or if you use programs that require a larger cache.
1. Click Start, click Run, and then type sysdm.cpl in the Open box.
2. Click the Advanced tab, and then click Settings under Performance.
3. Click the Advanced tab, and then use one of the following methods under Memory usage:

• Click Programs if you use your computer primarily as a workstation instead of as a server. This option allocates more memory to your programs.
• Click System cache if your computer is used primarily as a server or if you use programs that use a larger cache.

How to manually change the visual effects

Windows provides several options to set the visual effects of your computer. For example, you can show shadows under menus. Shadows give menus a 3-D look. You can configure Windows to display all the contents of a window while you move the window on your screen. To make large text more readable, you can display the smooth edges of screen fonts.Windows provides options to turn on all the settings (for best appearance), or none of the settings (for best computer performance). You can also restore the default settings. To change the visual effects, follow these steps:

1. Click Start, click Run, and then type sysdm.cpl in the Open box.
2. Click the Advanced tab, and then under Performance, click Settings.
3. Click the Visual Effects tab, and then use one of the following methods:
• Click Adjust for best performance to have Windows automatically adjust the settings for best performance.
• Click Adjust for best appearance to have Windows automatically adjust the settings for best appearance.
• Click Custom, and then select the check boxes for those items that you want to turn on. Clear the check boxes for the items that you want to turn off.
