Windows Xp hack for ADSL or loose 20% speed

If you are using windows XP you will loose 20% of your speed unless you do this

Increase BROADBAND:

this ones simple:
this is for broad band connections. I didn’t try it on dial up but might work for dial up.
1.make sure your logged on as actually "Administrator". do not log on with any account that just has administrator privileges.
2. start - run - type gpedit.msc
3. expand the "local computer policy" branch
4. expand the "administrative templates" branch
5. expand the "network branch"
6. Highlight the "QoS Packet Scheduler" in left window
7. in right window double click the "limit reservable bandwidth" setting
8. on setting tab check the "enabled" item
9. where it says "Bandwidth limit %" change it to read 0
reboot if you want to but not necessary on some systems your all done. Effect is immediate on some systems. some need re-boot. I have one machine that needs to reboot first, the others didn't. Don't know why this is.

This is more of a "counter what XP does" thing. In other words, XP seems to want to reserve 20% of the bandwidth for its self. Even with QoS disabled, even when this item is disabled. So why not use it to your advantage. To demonstrate the problem with this on stand alone machines start up a big download from a server with an FTP client. Try to find a server that doesn't max out your bandwidth. In this case you want a slow to medium speed server to demonstrate this. Let it run for a couple of minutes to get stable. The start up another download from the same server with another instance of your FTP client. You will notice that the available bandwidth is now being fought over and one of the clients download will be very slow or both will slow down when they should both be using the available bandwidth. Using this "tweak" both clients will have a fair share of the bandwidth and will not fight over the bandwidth.

Thanks for the info. I'm currently in the process of signing up with Plusnet for broadband and I use XP. Slightly concerned that this hasn't been ironed out by Plusnet but after reading comments from others (and I hope they are in the minority regarding number of customers) I'm getting distinctly concerned! - I have been with BTopenworld for 6month until changing to Plusnet and until this time EVERYTHING has been ok,polite,quick response etc (yep, a happy BT customer!!).

Don't be concerned, Plus are excellent. They have had a few problems of late but have worked extremely hard to get things back on track. I have been with Plus for over two weeks and like you was concerned as to whether I had made the right decision after reading all the angry users - but don't be. You have made the right choice!

RE: Windows Xp hack for ADSL or loose 20% speed

Totally agree... I'm into my second month with PlusNet and have had no complaints at all. OK so BT had some problems a couple of weeks ago, but that wasn't PlusNet's fault and was corrected quite quickly. I haven't found another ISP that is anywhere near as reliable as PlusNet.

Anyway, this 20% bandwidth thing... I was under the impression that this was only the case in XP Pro. I did a quick ADSL speed check on www.adslguide.org.uk this morning and was getting 480kbps download (usable) and 243 kbps upload ! It did mention something about reserved bandwidth. Including that I was getting about 590kbps download and 295 upload. Maybe this 20% thing is why there are two sets of figures. I have XP home edition. I will have a look tonight and see if I can change the bandwidth restriction in XP.

What does XP use this bandwidth for Huh

RE: Windows Xp hack for ADSL or loose 20% speed

Be very careful adjusting networking settings!
i wouldn't do it.

Why do people always want to go faster?.
you run the risk of messing up your computer just to get a tweek up than might not even be all that much of a difference anyway.

Download System Mechanic from 'www.iolo.com'
Iolo Technologies is trust worthy,
and will tweek XP up for you safely, with the option of putting ever setting back the way it was before yo started incase you have problems.
It also cleans every bit of junk out of your computer and fixes every kind of problem you can imagine!. I've been using this software for two years, and there is always an update version every month.

I'm writing this as i tried to tweek up Windows 98 SE when i was using it, and ended up screwing up my entire dialup networking settings so much, that the computer couldn't even detect the internet and make a connection.
and i had to reinstall everything. (Windows 9Cool

XP sends alot of stuff back to Microsoft, like error report and probably a few other things. so they can improve it, it is still fairly new and has bugs, well i have some.
Maybe it was designed to be that way, the 20% part.. be careful Smiley

:rollsmile: Cos we're Sp33d phr34kz !! :rollsmile:



i agree with your point tho, i'd like to hear from anybody who tries this, let me know whether it works or not, and whether you have had any probs in doing so.

Erm, not quite!

There is a lot of rubbish about this subject. Go to the Microsoft site and you will find this...

********************

***** Clarification about QoS in End Computers That Are Running Windows XP *****

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.

For more information about the QoS packet scheduler, refer to Windows XP Help. Additional information about Windows 2000 QoS is available in the Windows 2000 technical library.

***** Correcting Some Incorrect Claims About Windows XP QoS Support *****

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 of this article correctly describes the behavior of Windows XP systems.

*******************


So there you have it, you DO NOT lose 20% of your bandwidth. Basically just leave the setting alone, it does NOTHING to improve your connection.

An open mind is like a skip, somebody will just fill it with a load of rubbish.
