    Hello, have you tested your download/upload speed? Unfortunately, you hardly ever will reach the speed advertised by your ISP. Go to the link provided and check both your download and upload speed.


    Also, depending on what operating system you are running the half open TCP ports influence your speed. When XP came out, it had unlimited half open TCP connections, but when XP service pack 2 came out, it had a limit of 10. This limit was introduced to prevent virus, worms and malicious programs from spreading to other computers.
    This limit went away when vista service pack 2 came out. There is also no limit with windows 7.

    It also depends what else you are doing on your computer when you are downloading. You can not expect to reach good speeds if you are doing other heavy internet activities. If you want to reach good download speeds, do not do anything else online when you are downloading. Another important factor, is how far away you are from your ISP location. The farther away you are, the slower the connection. Also, you can improve your speed if you do your downloading whenever other people close to you are using their internet, specially if they are in the same node and ISP provider as you. Hope it helps

    If you use Windows XP Professional then it is possible to squeeze an extra 20% out of your internet connection. By default Windows XP Pro holds back 20% of your Internet speed for various services like windows update and spyware checks.

    If you want to tap into this locked speed then make the following changes:

    Go to Start-> Run-> and type gpedit.msc
    Expand the Administrative Templates branch
    Expand the Network tab
    Highlight QoS Packet Scheduler
    Click on Limit Reservable Bandwidth and check the ‘enabled’ box
    Then Change the Bandwidth limit % to 0 %
    Once you’ve done this click apply and restart your PC. After rebooting you should see a noticeable improvement in your net speed.

    How to increase your available bandwidth in windows 7?
    1)Go to run and type “gpedit.msc in it and hit enter, Local computer policy widows will open and go to the last option “All Settings”
    2)Find “Limit the bandwidth of Audio and video” and double click on it,now you will see it as not configured-disable it by clicking on the disable radio button
    3)Now on the top right hand corner of the same window click on next setting or search for-”Limit the size of sent file” will open disable it as well of if you want to keep it enabled then make the file size zero kilobytes
    4)Now hit ok and close the window

    Phase 1:Type "about:config" into the address bar of firefox and hit return. Scroll down and look for the following entries:


    * Alter the entries do as follows:

    Set "network.http.pipelining" to "true"

    Set "network.http.proxy.pipelining" to "true"

    Set "network.http.pipelining.maxrequests" to some number like 30.

    * Lastly right-click anywhere and select New-> Integer.
    Name it "nglayout.initialpaint.delay" and set its value to "0".

    Phase 2:Now download and install internet download manager

    download orbit downloader

    Phase 3:Download TCP optimizer

    When u open TCP Optimizer, don't do anything, just select the option 'Optimal Settings' & apply the changes.In the next box, press OK and restart the system.

    Other important factors that can mar your download speed are some other programs or processes running simultaneously on your computer. Make sure that you shut down all other open programs before beginning with your download. This would facilitate your computer to handle data transfer more resourcefully.

      As I pointed out in a comment to the article I recommended above, the 20% bandwidth reservation is partly a myth.

      Fact is that the 20% bandwidth reservation only comes into effect when Qos aware applications need bandwidth; in that case they can snatch up to 20%. It doesn't mean that 20% are blocked off all the time!

      However, I would reduce it to 0 anyways as it will have a temporary effect, for example when you're browsing and Windows decides to download an update. Unfortunately, gpedit.msc is not available in Home / Home Premium editions of Windows.

    can you please provide more information, for example...

    - Who is your internet service provider and what download speed do they promise?
    - What is your hardware setup for accessing the internet?
    - What operating system are you using?

    Any little details might be helpful in answering your question.
