Well, that's an interesting finding I haven't heard about before. But the folks at RealTechNews wrote, that Microsoft reserves 20% of your available bandwidth for its own purposes (suspect for updates and interrogating your machine etc).
Well, this shouldn't be a problem at all as long as you are connected to a broadband connection like DSL, etc. but 20 % is a lot if you are connected wireless via UMTS or HSDPA. Anyway, it wouldn't be Windows XP if there wouldn't be a hack at all, as Lockergnome explains:
- Click Start / Run
- Type: gpedit.msc
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
- 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%
Well done, I hope I will get more out of my UMTS connection now (with
which I'm writing this article because I'm abroad).
