Windows XP QOS Packet Scheduler

[Archman]

Hello,

Will changing the default setting of 20% to 0% lead to an increase in bandwidth that is noticeable?

It explains itself in windows by saying:

"Determines the percentage of connection bandwidth that the system can reserve. This value limits the combined bandwidth reservations of all programs running on the system.

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.

If you enable this setting, you can use the "Bandwidth limit" box to adjust the amount of bandwidth the system can reserve.

If you disable this setting or do not configure it, the system uses the default value of 20 percent of the connection.

Important: If a bandwidth limit is set for a particular network adapter in the registry, this setting is ignored when configuring that network adapter."

When XP first came out a lot of places said you needed to set it to 0 or you'd lose bandwidth. I haven't looked in awhile but I'm pretty sure that was just a myth and changing it to 0 doesn't really do anything. I haven't bothered to chang it to 0 in years.

Okay, I was not sure if it was true or not. I recall seeing some sites say yay, and some say nay. So I thought I would ask around here, and see what's said 🙂

As posted, this controls the amount of bandwidth that applications CAN reserve. It doesnt' mean that bandwidth is sitting unused when apps that don't reserve run. It just means that if an app DOES reserve bandwidth, how much of your overall bandwidth is it allowed to reserve.

You won't see any benefit in changing it from 20 to 0.
