Does the XP default reserved 20 broadband full release have any effect?

Hello! 1 This 20% default reserved bandwidth is reserved by Windows for system stability considerations, which optimizes the balance between network bandwidth and system security to the greatest extent. It is not recommended to release this 20% of the bandwidth.

Data overflows, redundant loop check failures, and so on are all potential problems that can occur. ）

2 If the main network is already very bad, then even if you add this 20% of the bandwidth channel, you will not see an effective improvement in network speed. After all, this reserved bandwidth refers to the transmission width of the channel, not the network traffic. It's like if you make the road wider, but there are still only so many cars on the road, and there is still so much traffic per unit of time, so there is basically no noticeable change. Above.

There is no such thing, and the 80% you said will only be occupied when the system is going to be used, and it usually has no effect.

That's reserved for QoS. The reserved bandwidth is used for a new technology introduced in Windows 2000, QoS (i.e., Quality of Service), and this is not necessarily used to use this 20% of the bandwidth, in fact, it will only be used when the QoS application programming interface is used to write an application that needs to access the network.

If these applications that use the QoS API do not access the network, the reserved bandwidth can still be used by other applications. Microsoft specifically addresses this issue in the codename.

This is explained in detail in the knowledge base. If we set it to 0%, it means that applications written using QoS APIs have to compete with other applications for limited bandwidth, and the possible consequence is that data that needs to be communicated first is not prioritized. Of course, QoS, a new technology designed to improve network quality, is no longer meaningful.

So that 20% broadband is almost meaningless.

Of course, it can be released, but the reserved bandwidth is to allow other programs to have the bandwidth to use the network, most of which are used by the windons themselves. If there is no demand, it can be released!

Start, Run, Open Group Policy.

Computer Configuration, Management Template, Network, QoS Packet Scheduler, click "Limit Reservable Bandwidth", change Unconfigured to Enabled, and change the bandwidth limit from 20% to 0% Apply, OK, OK

It's a lie if it's useless! Don't take those people's word for it! If it's useful, I don't care about the remaining 20%! The internet speed is still stuck!
