Hey guys! check this out, I got this tweak from tipidpc.com, a site that buy/sell/trade computer peripherals locally here in the Philippines. It has something to do with the QOS packet scheduler in Windows XP Professional Edition talking about it’s reserved bandwidth. I did a little research and here is what I got from speedguide.net.

“The default system behavior is that all 100% bandwidth is available, however, if there is a running application that indicates to the OS it needs to send high priority/real time data, then as long as it has the socket open, Windows XP will restrict “best effort” traffic to 80% of the bandwidth so that high priority traffic can be accommodated. Basically, applications can make this request to the operating system for QoS support using the QoS application programming interfaces (APIs) in Windows and this only applies if a specific app is requesting QoS.”

If you’d like to change how much bandwidth is reserved for QoS (the default is 20% of the total bandwidth), do the following:

1. Make sure you’re logged in as “Administrator” (not just any account with admin privileges).
2. Navigate to START>Run and type: gpedit.msc
3. Navigate to Local Computer Policy > Administrative Templates > Network > QOS Packet Scheduler
4. In the right window, double-click the limit reservable bandwidth setting
5. On the setting tab, check the enabled setting.
6. Where it says “Bandwidth limit %”, change it to read 0 (or whatever percentage you want to reserve for high priority QoS data)
7. Click OK, close gpedit.msc

Under START > My Computer > My Network Connections > View Network Connections, right-click on your connection and under Properties (where it lists your protocols), make sure QOS Packet Scheduler is enabled.

You need to reboot for changes to take effect.
Note: This tweak applies only to The Professional version of Windows XP.

I’ll try this on my end and will have an update later.

Update:

Here are the results that I got.

Before:

A pretty nice improvement from what I am getting before. How about yours? icon biggrin 20% Chance to Increase Bandwidth
