Speed up your internet speed by 20 percent

This is a nice little tweak to get 20% of bandwidth back.Microsoft reserve 20% of your available bandwidth for their own purposes (suspect for updates and interrogating your machine etc..).

    Click Start–>Run–>type “gpedit.msc” without the ”

  • This opens the group policy editor. Then go to

    Local Computer Policy–>Computer Configuration–>Administrative Templates–>
    Network–>QOS Packet Scheduler–>Limit Reservable Bandwidth

  • Double click on Limit Reservable bandwidth. It will
    say it is not configured, but the truth is under the
    ‘Explain’ tab :

    “By default, the Packet Scheduler limits the system to
    20 percent of the bandwidth of a connection, but you
    can use this setting to override the default.”

  • So the trick is to ENABLE reservable bandwidth, then
    set it to ZERO.

    This will allow the system to reserve nothing, rather
    than the default 20%.

  • works on XP Pro, 2000 and 2003 but not sure about
    other o/s’s.

  1. Has this increased your browsing speed. 20% should be a notable increase. Nice tip.

  2. Didn’t even know this was implemented. I’ll give it a try right away. Thanks for the tip!

  3. < <<---Moderated---->>>. Its a myth that has been floating around on the internet for years and I am surprised to see that people are still falling for it.

    You can read Microsoft’s response here

    There have been claims in various published technical articles and newsgroup postings that Windows XP always reserves 20 percent of the available bandwidth for QoS. These claims are incorrect. The information in the “Clarification about QoS in end computers that are Running Windows XP” section correctly describes the behavior of Windows XP systems.

    As in Windows 2000, programs can leverage QoS through the QoS application programming interfaces (APIs) in Windows XP. One hundred percent of the network bandwidth is available to be shared by all programs unless a program specifically requests priority bandwidth. This “reserved” bandwidth is still available to other programs unless the requesting program is sending data. By default, programs can reserve up to an aggregate bandwidth of 20 percent of the underlying link speed on each interface on an end computer. If the program that reserved the bandwidth is not sending enough data to utilize it completely, the unused portion of the reserved bandwidth is available for other data flows on the same host.

    This myth was debunked years ago. I found a tweakxp article regarding this that dates back to 2003.

    I hope this clears up any confusion :)
    This wont increase your internet speed by 20%. Even M$ is not stupid enough to do something like this.

  4. Dear pallab , I would appreciate if you are polite while commenting. Yeah its my mistake as I didnt do much research on this. I use 1mbps broadband connection , hence 20% increase hardly matter for me. Anyway thanks for shedding some light on this. Knowledge increase when shared .. :-D

  5. I am sorry you felt I was rude. Well I suppose BS came off as a strong word. However my intention was never to be disrespectful to you :) . As I mentioned in my original comment, I was just trying to clear up any confusion you had regarding the QoS bandwidth reservation setting.

    And you are one lucky guy to have 1mbps broadband.

  6. Its ok pallab. Yeah that word sounded strong and I was left with no other choice than to moderate it. I should say sorry for that.
    1 mbps in the office yaar, wish I had same thing at my room also :-(

  7. I have used the method exactly shown here and found that my internet speed has been increased by 25% so thanks a lot.

  8. It may be a debunked myth, but my max download went from 45KB/s to about 75KB/s after doing this.

  9. Thanks for the tip-I am going to try it out :) I don’t even know how much speed my Internet has but it is slow at times

  10. @tim Ahh , thanks for the info. Well, if it increased for you must do for others also :)

    @emmaS Try it out and if it works do leave a comment here
