Disabling Unused PORTS

I have just accidentally found out another way to give you an extra boost in windowsXP's boot performance. This is done by disabling your unused devices in Device Manager. for example, if you don't have input devices that are connected to one of your USBs or COM ports, disabling them will give you an extra perfromance boost in booting.

Go to Control Panel - System - Hardware tab - Device manager

Disable devices that you don't use for your PC and then restart. See the difference for yourself.

Perform a Boot Defragment: 

There's a simple way to speed up XP startup: make your system do a boot defragment, which will put all the boot files next to one another on your hard disk. When boot files are in close proximity to one another, your system will start faster. On most systems, boot defragment should be enabled by default, but it might not be on yours, or it might have been changed inadvertently.

            To make sure that boot defragment is enabled on your system, run the Registry Editor and go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction

Edit the Enable string value to Y if it is not already set to Y. Exit the Registry and reboot. The next time you reboot, you'll do a boot defragment.

Stopping Unneeded Startup Services and Making XP boot faster !

Along with the core operating system and programs that Windows XP runs when it starts, there is also a host of services involved. Many of these services are necessary for Windows XP to operate correctly. However, many of them are for features in Windows XP that you may not use at all. You can peruse the services and disable any service that you do not want to run. The fewer services that run, the more quickly Windows XP will boot. To reduce the number of services that start on bootup, you can access two different areas of Windows XP.

1. The first is the System Configuration Utility. You can do that by entering the command “msconfig” in the run menu.

            Start  Run “msconfig” (without quotes) || Hit Enter

The Services tab shows you the services that start when the computer boots. You can stop a service from starting by simply clearing the check box next to the service and clicking OK.

2. Another way to disable services that you may prefer because the interface gives you more information about the service in question.

- Open Control Panel - Administrative Tools - Services or Start  Run “services.msc” || Hit Enter

- Take a quick look at common services you may want to live without:

Automatic Updates: This service enables Windows XP to check the Web automatically for updates. If you don't want to use Automatic Updates, you can disable the service.

Computer Browser: If your computer is not on a network, you don't need this service. If you are on a network, leave it alone.

DHCP Client: If you are not on a network, you do not need this service. If you are on a small workgroup, you can still increase boot time by configuring manual IP.

DNS Client: If you are not on a network, you do not need this service.

Error Reporting and Event Log: You don't have to use these services but they can be very helpful, so I would leave them configured as automatic.

Fax: If you don't use your computer for fax services, you can disable this one.

Help and Support: Disable if you never use the Windows XP Help and Support Center.

IMAPI CD-Burning COM: This service enables you to burn CDs on your computer.If you never burn CDs, you can disable the service without any second thoughts.

Indexing Service: Your computer keeps an index of all the files. But if you rarely search for files, the service is just a resource hog. You can stop it.

Windows Firewall/Internet Connection Sharing: If you do not use these features, plz disable.

Infrared Monitor: If you do not use infrared devices, you can disable this service.

Messenger: This service sends alert messages on a local area network (it is not the same as Windows Messenger). If you are not on a network, you can disable this service.

Print Spooler: If you do not do any printing from the computer, you can disable this service. If you print, make sure you leave it as automatic.

Remote Registry: This service allows remote users to modify the Registry on your computer. If you are not on a network, you can disable this service.

System Restore Service: This service allows you to use System Restore. If you have turned off System Restore anyway, you do not need to turn off the service.

Themes: If you do not use themes, you can disable this service.

Windows Image Acquisition: If you do not use scanners or digital cameras, you can disable.

Wireless Zero Configuration: If do not use wireless networking devices, you can disable.

Writing the first JSP page

A JavaServer Page, technically speaking, is a web page which is embedded Java code. Java code is executed in the server side and merge with the static elements of the web page such as HTML tags... then returns the result which is plain old HTML code, JavaScript and CSS to the web browser.

This is the source code of our first JSP page which prints the simple famous greeting in programming world "Hello World" on the web browser.

JSP Page is composed of HTML and Java code. The Java code is embedded between thenotations <% and %> and it is called Scriptlet. Inside the scriptlet block, we call the method println of the out object to print the text "Hello World".
