Little-known Windows XP optimization

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_MacHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\SecondLevelDataCache]";

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

1. Run "regedit";

2. Go to [HKEY_LOCAL_MacHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\IoPageLockLimit];

3.According to you The memory modifies its hexadecimal value:

64M: 1000;

128M: 4000;

256M: 10000;

512M or more : 40000.

4. Restart

Third, read-ahead settings to increase speed

xp use read-ahead settings for this new technology
to improve System speed. If you have PIII 800, 512M memory or more, it is recommended to modify:

1. Run "egedit"

2. Go to [HKEY_LOCAL_MacHINE\\SYSTEM\\CurrentControlSet\\Control\\Session Manager\\Memory Management\\ PrefetchParameters\\EnablePrefetcher];

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. Suggestion, define the environment to raise funds #╟:\\Windows\\prefetch)

V. Reduce the disk scan waiting time

Under DOS, type “chkntfs/t:0” < Br>

0: Indicates that the waiting time is 0 seconds

VI. Turn off 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 "Properties".

3. Cancel "Use index to find files quickly".

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" can be modified This bug.

2. Run "regedit"

3. Go to [HKEY_CURRENT_USER\\Control Panel\\Mouse]

"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

The benefits of ntfs needless to say, but there are also deficiencies.

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

Run "regedit"

In HKEY_LOCAL_MacHINE\\SYSTEM\\CurrentContolSet\\Control\\Filesystem), add DWord with a value of 1.
