Little-known Windows XP optimization

First, modify the cpu's secondary cache

Under normal circumstances, xp will automatically identify the cpu's secondary cache. But sometimes xp won't do this, so you need to manually optimize to improve the performance of the cpu.

1.Run"regedit";

2. Go to "[HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementSecondLevelDataCache]";

3. Modify his decimal:

AMD Duron: 64(kb);

CeleronA/celeron2:128;

PII mobile/PIII E(EB)/P4/AMD K6-3/AMD THUNDERBird/Cyrix III: 256;

AMD K6-2/PII/PIII katmai/AMD Athlon: 512;

PII Xeon/PIII Xeon: 1024;

4. Restart.

Second, modify the disk cache to speed up xp

Disk caching plays a crucial role in xp operation, but the default I/O page file is conservative. Therefore, it is better to use different disk caches for different memories.

1. Run "regedit";

2. Go to [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementIoPageLockLimit];

3. Modify its hexadecimal value according to your memory:

64M: 1000;

128M: 4000;

256M: 10000;

512M or more: 40000.

4.Restart

Third, read-ahead settings to increase speed

xp uses the new technology of read-ahead settings to increase system speed. If you have PIII 800, 512M memory or more, it is recommended to modify:

1. Run “egedit”

2. Go to [HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParametersEnablePrefetcher];

3. Set the value 0,1,2,3. 0-Disable, 1-ready application, 2-start pre-read, 3-pre-read both ("3", recommended).

4. Restart.

This will reduce startup time.

Fourth, clear the pre-read file

When xp is used for a period of time, the files in the pre-reading folder will become very large, there will be dead chain files, which will slow down the system. time. It is recommended to delete these files on a regular basis. (c:windowsprefetch)

V. Reduce disk scan wait time

Under dos, type “chkntfs/t:0”

0: indicates wait time is 0 Seconds

Sixth, close the disk index

Xp records all the files for quick search. If you don't find the file often, you can close it.

1. Open my computer

2. Right click on the drive and select “Attributes”.

3. Cancel “use index to quickly find files”.

Seven, fix the mouse acceleration bug

1. When playing quake3, cs in xp, the mouse acceleration has problems and the gunshot becomes inaccurate, the tweak named "yinxs" Modify this bug.

2. Run “regedit”

3. Go to [HKEY_CURRENT_USERControl PanelMouse]

"SmoothMouseXCurve"=hex:00,00,00,00,00,00 ,00,00,00,a0,00,00,00,00,00,00,00,40,

01,00,00,00,00,00,00,80,02,00 ,00,00,00,00,00,00,05,00,00,00,00,00

"SmoothMouseYCurve"=hex:00,00,00,00,00,00,00 ,00,66,a6,02,00,00,00,00,00,cd,4c,

05,00,00,00,00,00,a0,99,0a,00,00 ,00,00,00,38,33,15,00,00,00,00,00

4.Restart

Eight, optimize ntfs file system

ntfs Needless to say the benefits, but there are also deficiencies.

Cancel the last disk access update, which slows down for large partitions.

Run “regedit”

In HKEY_LOCAL_MACHINESYSTEMCurrentContolSetControlFilesystem), add DWORD with a value of 1.
