Improved Bandwidth Usage

I came across this:

"By default Windows XP reserves up to 20 percent of your connections bandwidth.

To override this reserve take the following steps.

Make sure you Log on as Administrator, not as a user with Administrator privileges.

* Start-> Run-> type gpedit.msc
* You will see [Local Computer Policy]
* Expand the [Administrative Templates] branch
* Expand the [Network] branch
* Highlight [QoS Packet Scheduler]
* Double-click [Limit Reservable Bandwidth]
* Check [Enabled]
* Change [Bandwidth limit %] to 0 %
* Click [Apply] [OK]

* Restart

Effect is immediate."

Is this accurate? Would it actually show a performance boost (say in online gaming)?

thx

According to Microsoft, the claim is incorrect:

http://support.microsoft.com/default...EN-US;q316666&

e.g.

"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."

"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."

OK - thank you. What I get from that is, if playing an online game and nothing else is running through the router, the game gets 100% of the bandwidth UNTIL some other app wants to send data.

Windows does not load balance, therefore if you have more than one application sending data, then the bandwidth is shared. You will be surprised how many apps want to send usage data or look for updates.
