tcpackfrequency?注册表 带宽限制?win7 20%网速?Windows XP修改注册表改善延迟的方法，实

你是否正在寻找关于tcpackfrequency的内容？让我把最直接的东西奉献给你：

请先读一下条例
1 - 这个修改可能会有副作用，比如降低你的下载速度或者影响你其他软件的运作（不过在我这边，没这些问题）
2 - 如果你不确定你在做什么，那请不要继续。我不希望对因为你错误修改注册表而导致的机器崩溃负责
2.1 - 再次严正申明，如果你不知道你在做什么，请不要继续。因为无论如何延迟问题会在一到两周内被修复（官方补丁的修复不会和其他软件冲突）
3 - 如果你的注册表里没有HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\ 路径，你可以从
4 - Windows Vista用户请去[ ?topicId=3271071466&postId=33532161447&sid=1#190这里 ]看

"1 - tcpackfrequency - NOTE if you are running Windows Vista this setting may not have any effect - a hotfix is needed which i'm tracking down. This works fine under Windows XP
Type "regedit" in windows "run.." dialog to bring up registry menu
Then find:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\
There will be multiple NIC interfaces listed in there, find the one you use to connect to the internet, there will be several interfaces listed (they have long names like {7DBA6DCA-FFE8-4002-A28F-4D2B57AE8383}. Click each one, the right one will have lots of settings in it and you will see your machines IP address listed there somewhere. Right-click in the right hand pane and add a new DWORD value, name it tcpackfrequency, then right click the entry and click Modify and assign a value of 1.
You can change it back to 2 (default) at a later stage if it affects your other TCP application performance. it tells windows how many TCP packets to wait before sending ACK. if the value is 1, windows will send ACK every time it receives a TCP package.
1 - tcpackfrequency - 注意如果你使用Windows Vista，这个修改不会有任何作用。这个修改只作用于Windows XP
在开始->运行内输入"regedit"打开注册表编辑器。
然后找到HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces\
你会发现有许多下层目录，找到你用来连接网络的那个，通常名字比较长，比如{7DBA6DCA-FFE8-4002-A28F-4D2B57AE8383}。点击每一个，正确的那个会有许多设置项并且你会在其中找到你的IP地址，。
右击右边空白处，新建一个DWORD值，命名为tcpackfrequency（请复制红字防止打错），然后右击修改其值为1。
如果稍后你发现这个修改影响你其他TCP请求的运作，你也可以修改成2（默认值）。这个值告知windows在发送ACK前要等多少TCP包。如果它的值是1，windows将会在每收到一个TCP包后发送ACK。
2 - TCPNoDelay
This one is pretty simple (Discussed here)
Type "regedit" in windows "run.." dialog to bring up registry menu
Then find:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSMQ\Parameters
Right-click in the right hand pane and add a new DWORD value, name it TCPNoDelay, then right click the entry and click Modify and assign a value of 1.
