(TRICK) mengoptimalkan internet bandwidth


mengoptimalkan bandwidth dengan ngutik2 properti QOS di Window XP Pro
Utak-utik ini cuman bisa buat Windows XP edisi Pro
Idealnya, bandwidth bisa dipake 100%, tapi, jika ada aplikasi yang menyatakan kepada OS bahwa aplikasi butuh untuk mengirim data yang prioritasnya tinggi, maka jika selama tersedia socket, Windows XP akan membatasi maximum bandwidth pada level 80%, sehingga aplikasi dengan prioritas dapat terakomodasi. Umumnya, si aplikasi dapat mengajukan permintaan ini ke system, utk mendukung QoS, dengan menggunakan QoS API nya Windows, ini hanya bisa jika si aplikasi meminta QoS.

Jika jatah bandwidth untuk QoS ( yang normalnya 20% ) ingin dirubah, ikuti langkah2 berikut ini:

1. Pastikan anda log-in sebagai "Adminstrator"
2. Klik Start -> Run, ketik: gpedit.msc, ini akan membuka Group Policy windows.
3. Pilih Local Computer Policy >Computer Configuration> Administrative Templates > Network > QOS Packet Scheduler
4. Di window bagian kanan, double-click the limit reservable bandwidth setting.
5. Di setting tab, beri tanda check pada enabled setting.
6. Pada tulisan "Bandwidth limit %", rubahlah menjadi 0 (atau berapa saja yangmau dialokasikan ke QoS)
Biasanya Packet Scheduler membatasi system untuk mengalokasikan 20 percent dari bandwidth, tapi ini bisa di rubah."
jadi tricknya adalah: reservable bandwidth dibuat ENABLE, dan diset ke NOL.
Ini artinya tidak ada bandwidth yang dialokasikan ke QoS, yang biasanya 20% di booking.
7.Click OK, close gpedit.msc

Klik START > My Computer > My Network Connections > View Network Connections, klik kanan di 'your connection' pilih Properties (yang ada daftar protocol), pastikan QOS Packet Scheduler di beri tanda check.

















WinXP Speed-Up tricks n Tips
10 Simple Ways To Speed Up Windows XP
=====================================

1. Disable Indexing Services

Indexing Services is a small little program that uses large amounts of RAM and can often make a computer endlessly loud and noisy. This system process indexes and updates lists of all the files that are on your computer. It does this so that when you do a search for something on your computer, it will search faster by scanning the index lists. If you don't search your computer often, or even if you do search often, this system service is completely unnecessary. To disable do the following:

1. Go to Start
2. Click Settings
3. Click Control Panel
4. Double-click Add/Remove Programs
5. Click the Add/Remove Window Components
6. Uncheck the Indexing services
7. Click Next

2. Optimise Display Settings

Windows XP can look sexy but displaying all the visual items can waste system resources. To optimise:

1.Go to Start
2. Click Settings
3. Click Control Panel
4. Click System
5. Click Advanced tab
6. In the Performance tab click Settings
7. Leave only the following ticked:
- Show shadows under menus
- Show shadows under mouse pointer
- Show translucent selection rectangle
- Use drop shadows for icons labels on the desktop
- Use visual styles on windows and buttons

3. Disable Performance Counters

Windows XP has a performance monitor utility which monitors several areas of your PC's performance. These utilities take up system resources so disabling is a good idea.

To disable:

1. download and install the Extensible Performance Counter List
2.Then select each counter in turn in the 'Extensible performance counters' window and clear the 'performance counters enabled' checkbox at the bottom.button below.

4. Speedup Folder Browsing

You may have noticed that everytime you open my computer to browse folders that there is a slight delay. This is because Windows XP automatically searches for network files and printers everytime you open Windows Explorer. To fix this and to increase browsing significantly:

1. Open My Computer
2. Click on Tools menu
3. Click on Folder Options
4. Click on the View tab.
5. Uncheck the Automatically search for network folders and printers check box
6. Click Apply
7. Click Ok
8. Reboot your computer

5. Improve Memory Usage

Cacheman Improves the performance of your computer by optimizing the disk cache, memory and a number of other settings.

Once Installed:

1. Go to Show Wizard and select All
2. Run all the wizards by selecting Next or Finished until you are back to the main menu. Use the defaults unless you know exactly what you are doing.
3.Exit and Save Cacheman
4.Restart Windows

6. Optimise your internet connection

There are lots of ways to do this but by far the easiest is to run TCP/IP Optimizer.

1. Download and install
2. Click the General Settings tab and select your Connection Speed (Kbps)
3. Click Network Adapter and choose the interface you use to connect to the Internet
4. Check Optimal Settings then Apply
5. Reboot

7. Optimise Your Pagefile

If you give your pagefile a fixed size it saves the operating system from needing to resize the page file.

1. Right click on My Computer and select Properties
2. Select the Advanced tab
3. Under Performance choose the Settings button
4. Select the Advanced tab again and under Virtual Memory select Change
5. Highlight the drive containing your page file and make the initial Size of the file the same as the Maximum Size of the file.

Windows XP sizes the page file to about 1.5X the amount of actual physical memory by default. While this is good for systems with smaller amounts of memory (under 512MB) it is unlikely that a typical XP desktop system will ever need 1.5 X 512MB or more of virtual memory. If you have less than 512MB of memory, leave the page file at its default size. If you have 512MB or more, change the ratio to 1:1 page file size to physical memory size.

8. Run BootVis - Improve Boot Times

BootVis will significantly improve boot times

1. Download and Run
2. Select Trace
3. Select Next Boot and Driver Trace
4. A Trace Repetitions screen will appear, select Ok and Reboot
5. Upon reboot, BootVis will automatically start, analyze and log your system's boot process. When it's done, in the menu go to Trace and select Optimize System
6. Reboot.
7. When your machine has rebooted wait until you see the Optimizing System box appear. Be patient and wait for the process to complete

9. Remove the Desktop Picture

Your desktop background consumes a fair amount of memory and can slow the loading time of your system. Removing it will improve performance.

1. Right click on Desktop and select Properties
2. Select the Desktop tab
3. In the Background window select None
4. Click Ok

10. Remove Fonts for Speed

Fonts, especially TrueType fonts, use quite a bit of system resources. For optimal performance, trim your fonts down to just those that you need to use on a daily basis and fonts that applications may require.

1. Open Control Panel
2. Open Fonts folder
3. Move fonts you don't need to a temporary directory (e.g. C:\FONTBKUP?) just in case you need or want to bring a few of them back. The more fonts you uninstall, the more system resources you will gain.
