To improve performance when loading windows xp is by reduce the program running on startup.
Step One:
Press Start and select Run and enter the command msconfig.



After system configuration opened then select the startup tab and uncheck the list of program that you don’t want to run at startup and click apply and ok.

or select disable all if you desire no programs running at startup
Step Two:
The next step is by disable some running services. To disable some running services, open services.msc through the run or through the control panel. Select the service you wish to disable and then right click and chose properties, on the properties select disabled on the startup type menu.
Here are some services that I recommend for the disabled:
- Alerter
- Automatic Updates(If you do not want to update)
- ClipBook
- Error Reporting Service
- Help And Support
- IIS Admin
- Indexing Service
- Messeger
- Net Logon
- NetMeeting Remote Desktop Sharing
- Network DDE
- Network DDE DSDM
- Network Provisioning Service
- Print Spooler (if you do not use the printer)
- Remote Desktop Help Session Manager
- Remote Registry
- Routing and Remote Access
- Secondary Logon
- System Restore Service(not recomended for all user)
- TCP/IP NetBIOS Helper
- Telnet
- WebClient
- Windows Firewall/Internet Connection Sharing (ICS)(if you use antivirus software)
- Windows Time
- WMI Performance Adapter
- World Wide Web Publishing
I hope these tips can be useful for you.

This syntax is used to calculate the sum of all values that are in a field.
Here for the example :
SELECT * FROM your_table LIMIT 0, 10
//This will SHOW 10 row of your TABLE start FROM row 1 TO 10.
SELECT * FROM your_table LIMIT 10, 10
//This will SHOW 10 row of your TABLE start FROM row 11 TO 20.
SELECT * FROM your_table WHERE your_column LIKE %'value'%
//This will SHOW ALL row FROM your COLUMN that contain the value.
