Disabling the paging file

Users of computers with a large amount of RAM have the ability to stop the operating system from pushing any data out into the paging file. This will allow for the faster memory management and memory access that is physically possible for your RAM. Reading and writing directly to the RAM is always significantly faster than having to use the page file. Reading and writing to the paging file requires multiple steps and that takes time. Moreover, reading from the hard drive is nowhere as fast as reading from the RAM.

If your system has a large amount of RAM, over 1 gigabytes, then you can consider disabling the paging file. If you have less than 1 gigabyte of RAM, do not even consider disabling the paging file or else you will be running into problems.

What can happen if you disable your paging file? If you have enough RAM, then nothing. But if you do not have enough RAM, then if you run a large program such as Photoshop and are working on a large image, you will run into out of memory errors and the application will crash, causing you to lose all of your work. This is a pretty extreme example, but it can happen.

Basically, stick to the 1 gigabyte minimum and you will have no problems. But be aware that if you ever choose to run some memory-intensive applications, such as rendering a two-hour 3D movie, you could run out of memory easily.

So, now that I have warned you, you are ready to follow these steps to disable the paging file:

1. Enter System Properties, either by right-clicking the My Computer icon on the desktop and selecting Properties or by doing the same to the My Computer icon in the Start Menu.

2. Once the System Properties window has loaded, click the Advanced tab and then click the Settings button under Performance.

3. Once you are in the performance options, click the Advanced tab again.

4. Click the Change button that is located under the Virtual Memory section.

5. This will load the Virtual Memory screen. Locate and select the No Paging File radio button, under the Paging File Size for Selected Drive section.

6. Click the Set button and then click OK three times and you are finished. After you reboot, your page file will be disabled.

Feel free to delete the pagefile.sys file from your hard drive after you reboot to claim some extra few hundred megabytes of free space.

If you do not have enough RAM to disable the paging file completely, follow the directions in the next section to adjust the size of the paging file for best performance.

Using the quick boot feature of the BIOS

All systems initialize in more or less the same way. During the power on self-test mentioned earlier, the BIOS checks the hardware devices and counts the system memory. Out of all of the different types of system memory, the random access memory, better known as RAM, takes the longest to be counted. Counting the RAM takes time, and on a machine that has large amounts of RAM, this calculation can take several seconds. For example, a machine that has 512MB of RAM may take up to 3 seconds just to count the memory. On top of the RAM counting, a few other tests need to be done because your computer wants to make sure that all of the hardware in your computer is working properly. All of these system tests are not needed every time you boot, and can be turned off to save time. Most BIOS's offer a feature called quick boot. This feature will allow the user to turn off these tests. Other BIOSs only allow you to turn off the memory check, which will still cut down on a lot of time....

Rapidshare Timelimit

Directions Rapidshare traces the users IP address to limit each user to a certain amount of downloading per day. To get around this, you need to show the rapidshare server, a different IP address. You can do this one of multiple ways. Requesting a new IP address from your ISP server. Here's how to do it in windows: 1. Click Start 2. Click run 3. In the run box type cmd.exe and click OK 4. When the command prompt opens type the following. ENTER after each new line. ipconfig /flushdns ipconfig /release ipconfig /renew exit 5. Erase your cookies in whatever browser you are using. 6. Try the rapidshare download again. Frequently you will be assigned a new IP address when this happens. Sometime you will, sometimes you will not. If you are on a fixed IP address, this method will not work. To be honest, I do not know how to do this in linux/unix/etc. If this works for you, you may want to save the above commands into a batch file, and just run it when you need it.

File and Folder Permissions

Windows XP Professional boxes running the NTFS file system have the capability to set indi vidual file permissions on both files and folders. File and folder permissions allow you to specify exactly who will be able to read, write, execute, and even list or access a folder. So, file and folder permissions can be a very powerful tool to protect your data from others' eyes. If your file system is FAT32, then you will not be able to set permissions. Fortunately, an easy way exists for you to convert your FAT32 file system to NTFS. Do a search in the Windows Help and Support Center for Convert to NTFS and you will be shown directions on how you can go about converting your drive's file system. Setting the permissions on with a lot of control requires you to disable simple file sharing and security. To do so, follow these steps: 1 . Open up any folder on your computer and expand the Tools menu and select Folder Options. 2 . Click the View tab and scroll to the bottom of the Adv...
