Ifølge
den engelske nyhedstjeneste The Register "stjæler" styresystemet
Windows XP hele 20 procent af al tilgængelig båndbredde. Synderen er
den såkaldte QoS (Quality of Service) packet scheduler, der
reserverer båndbredden til vigtige applikationer og til optimering
af netværket.
Tanken bag QoS er ikke dårlig. I et normalt kontormiljø benyttes QoS
til at sikre, at eksempelvis netværket kører optimalt. Programmet
sikrer, at ens maskine ikke bryder ned, fordi en anden på netværket
overbelaster netværket ved for eksempel at downloade film eller
andre store filer.
Men
for privatpersoner, der kun har en computer i hjemmet, er QoS ikke
specielt bevendt. Snarere tværtimod.
XP reserverer de 20 procent bådnbredde selv om man lukker QoS ned.
Men det
er muligt at indstille hvor meget båndbredde QoS skal reservere via
filen gpedit.msc. En detaljeret guide kan findes i linket nedenfor:

Make sure
your logged on as Administrator. Do not log on with any

- In the password field type the password for the administrator
(if you don't have one leave blank) and press OK
-
Click on the
Start button and select run.
-
Type
gpedit.msc in the text box and click OK
-
Once the
program loads, expand the Computer configuration branch.
-
Expand the
Administrative templates branch.
-
Expand the
Network branch.
-
Highlight
the QoS Packet Scheduler in left window.
-
In right
window double click the limit reservable bandwidth setting
-
On setting
tab check the enabled option.
-
Where it
says Bandwidth limit %, change it to read what ever percent
you want to reserve for QoS-aware applications.
-
Click OK and
exit the group policy editor.
-
Go to your
Network connections (start->my computer->my network connection->
view network connections).
-
Right click
on your connection, choose properties then under the General or
the Networking tab (where it lists your protocols) make sure QoS
packet scheduler is enabled.
-
Now just
reboot your computer and you are all done.
When a
QoS-aware program is in use it will reserve the allocated amount of
bandwidth and that will take away form other non QoS-aware programs.
However, once the QoS-aware application is closed or closes the
