INCREASE bandwidth by "20%"

12:03 PM 1 comment

Microsoft reserves 20% of your available bandwidth for their own purposes like
Windows Updates and interrogating your PC etc. Click Start then Run and type
"gpedit.msc" without quotes. This opens the group policy editor. Then go to: Local
Computer Policy Computer Configuration Administrative Templates Network
QOS Packet Scheduler and then to LimitReservableBandwidth. Double click on
Limit Reservable bandwidth. It will say it is not configured, but the truth is under the
'Explain' tab i.e."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%.It works on Win 2000 as well.

WRONG - Will do nothing.
By default 100% of bandwidth is available to all applications. Windows reserves nothing. However, a QOS aware application can request priority bandwidth. But even if this occurs, there will be no bandwidth reduction unless the application is actively using it. Any unused bandwidth will be available to other applications.

Incidentally, Windows Update does not use QOS. It actually has lower priority than other applications and uses only bandwidth other applications are not using.
