Vista之家（www.vista123.com）：稀奇古怪，老外说播放音乐竟然降低Windows Vista网速

　　自从Vista发布起，国外的社区就充满了抱怨，称Vista的网络性能要大大低于Windows XP。

　　而来自2CPU Forum的最新帖子中，网友们都不同程度地感觉到了一点,那就是：播放音乐会明显降低网络速度,经过测量，性能降低5-10%不等.。为什么声卡发声会引起网络这么大的波动，现在谁也说不明白，赶快召唤微软客服吧！

　　Vista之家8月27日最新消息，微软针对此事已经做成正式官方回应，详情请看：

Interesting thing about slow vista network speed

background - M2N32-SLI DELUXE, 5600+ cpu, 2Gb ram, dual boot system xp and vista

on xp the network speed was between 30-50%
on vista it was stuck at just over 5%

so I followed all the advice about disabling autotuning etc, tried setting all the differerent lan driver settings, played with the tcp window size, latest drivers etc ....
none of it made a bit of difference, I was still stuck on 5% usage <grrrr>

until.... I stopped playing music...
doesn't matter what I play back music with, if it's playing or paused the lan speed seems to be locked at the 5%
stopping playback or quitting the player lets the file copy go to the 30-50% instantly

oddly, if I play a video, the lan transfers go up to 10%

playing an mp3 and video at the same time gives the same 10% and the usage stays the same even if the video is closed

after that the lan is limited to 10% when any audio/video programs are playing (as soon as they're closed it jumps back up to 30-50%, start them and it's down to the 10% again)

I can see it's not cpu usage, as it happens even while the video/audio is paused

In summary - not a clue why it happens , but I've seen this behaviour on a few different machines now．
