windows-server-2008 – 不明原因的慢速千兆网络速度

更新

好的,我已经尝试了下面的答案,没有任何改变.我已经将笔记本电脑中的芯片组识别为NVIDIA nForce 520.我为nForce 520下载了最新的Vista x64驱动程序(NVIDIA还没有针对Win 7芯片组的任何驱动程序).我已经尝试安装附带的防火墙软件(想想也许是干扰 – 它不是).我已经完全卸载了我的防病毒软件(我正在使用Avast！),认为它的网络过滤器驱动程序可能会导致问题,这也没有帮助.

我把笔记本电脑带到兄弟家里,能够通过100Mbit网络以10-12 MB / s的速度复制文件,所以我不认为这是硬件.

我运行iperf有一些令人惊讶的结果：
从笔记本电脑发送到服务器的iperf(上传)

为了比较,这里是HTPC和服务器之间的iperf数字

Server: Naru,Host: CC (CC sends to Naru)
iperf -c naru:        0.0-10.0 sec   363 MBytes   305 Mbits/sec
iperf -c naru -w 64k: 0.0-10.0 sec  1.06 GBytes   912 Mbits/sec

Server: CC,Host: Naru (Naru sends to CC)
iperf -c cc:        0.0-10.0 sec   322 MBytes   270 Mbits/sec
iperf -c cc -w 64k: 0.0-10.0 sec  1020 MBytes   855 Mbits/sec

使用wireshark观察从服务器到笔记本电脑的传输,可以输入以下大量条目：

在这一点上,我完全彻底地失去了接下来要尝试的东西.
