Windows reserves 20% of your internet bandwidth. Microsoft reserve 20% of your available bandwidth for their own purposes (suspect for updates and interrogating your machine etc..). A nice little tweak for XP will unleash all the bandwidth for you to use.
Here's how to get it back:
- Click Start
- type "gpedit.msc" without the "
- Local Computer Policy
- Computer Configuration
- Administrative Templates
- QOS Packet Scheduler
- Limit Reservable Bandwidth
"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 and restart your computer.
This will allow the system to reserve nothing, rather than the default 20%.
Feel free to leave feedbacks and let me know if this worked for you.
