Increase Multithread Download Speed by Disable Vista Auto Tuning on TCP/IP增加的多線程的下載速度由禁用Vista的自動調諧TCP / IP協議

In Windows Vista, Microsoft incorporates new TCP/IP stack which features Auto Tuning capability.在Windows Vista中，微軟將新的TCP / IP協議棧功能自動調節能力。 The Auto Tuning function able to adjust and optimize TCP/IP connection based on network utilization in order to increase the transfer rate throughput.自動調諧功能能夠調整和優化TCP / IP連接基於網絡的利用，以提高傳輸速率的吞吐量。 In theory the new stack suppose to do so, however, in practical, Auto Tuning feature may not work correctly to bring better performance for network downloading and web surfing.在理論的新棧假設這樣做，但是，在實際的，自動調整功能可能無法正常工作帶來更好的性能，為網絡下載和網上衝浪。

Other than the problems mentioned以外的其他所提及的問題 previously以前 , Auto Tuning may also cause reduce the rate of establishing network connection, especially when using third-party driver for the network card. ，自動調整也可能導致減少的速度建立網絡連接，尤其是當使用第三方驅動程序，為網路卡。 Other possible problems are Windows Live Messenger slow sign in process or unable to login, slow speed when viewing shared resources in LAN environment, or slow download speed when using multi-thread multiple-concurrent-connection programs such as FlashGet, BT clients such as uTorrent, BitComet and etc comparing with the download speed possible to get in WinXP.其他可能出現的問題是Windows Live Messenger的緩慢，簽署過程中或無法登錄，速度慢，當查看共享資源在局域網環境中，或緩慢的下載速度時，使用多線程的多並行連接的程序，如網際快車，英國電信的客戶，如utorrent ， bitcomet等比較，與下載速度可能得到在winxp 。

All these symptoms may not caused by “Auto Tuning”, however, trying to disable Auto Tuning on TCP/IP in Vista to verify if the problems have been solved is a good way to ensure that it’s not the culprit.所有這些症狀可能不是所造成的“自動調節” ，但是，試圖禁用自動調整TCP / IP協議在Vista驗證，如果問題已經解決是一個好方法，以確保它不是罪魁禍首。

Disable Receive Window Auto-Tuning Level on TCP/IP 禁用接收窗口自動調諧的水平上的TCP / IP

1. Open a command prompt with administrator rights打開一個命令提示符具有管理員權限 . 。
2. Input the following command, and press Enter when done:輸入以下命令，並按下Enter時，做了：

   netsh int tcp set global autotuninglevel=disable在netsh詮釋的TCP設置全球autotuninglevel =禁用

3. Restart the system.重新啟動系統。

If the problem still exists, it’s more likely caused by other reasons such as如果問題依然存在，它的更可能造成的其他原因，如 maximum concurrent connection attempt limit最大並發連接嘗試的限制 . 。 In this case, we can re-enable the Auto Tuning for good.在這種情況下，我們可以重新啟用自動調整為好。

Enable Receive Window Auto-Tuning Level on TCP/IP 使接收窗口自動調諧的水平上的TCP / IP

2. Input the following command, and press Enter when done:輸入以下命令，並按下Enter時，做了：

   netsh int tcp set global autotuninglevel=normal在netsh詮釋的TCP設置全球autotuninglevel =正常

3. Restart the system.重新啟動系統。
