Win7 system Speed not how to do?
At the command prompt, enter:
When netsh interface tcp show global, the Receive Window auto-adjust level is normal, and the problem is here, just close it.
It is also a one-line command (requires Administrator privileges to operate):
netsh int tcp set global autotuninglevel=disabled will receive a "OK" message, and try again to feel the speed of the network coming back a little bit (well, it may also be a psychological effect).
What if you're still using Windows 7? With the small weave together to relive the old tricks of the years!
After clicking "Start" in the lower left corner and entering "gpedit.msc" in "Run", in the left "Computer Configuration-Administrative Templates-Network-qos Packet Scheduler", double-click "limit to retain bandwidth".
Select "Enabled" to change the system default of 80% to 0.
In Microsoft's technical resource plan, applications running on Windows XP and above can share all of the network bandwidth unless the application specifically requests priority bandwidth. However, if the requested application does not send data, these "scheduled" bandwidth is still available for use in other applications.
In other words, if our PC does not have those "rogue" applications, always want to do a variety of ways to occupy network bandwidth, it is not to feel the changes brought about by the speed change. If you are after this change, and found that the speed of faster, then quickly check the installation of those applications before so overbearing it!
