Microsoft Networking vs Playing an MP3

• They just said a 90% performance hit to an unrelated system is normal? So where's the "defective by design" tag?
• Back in 1994, I bought a Power Macintosh 7100. One of the first PPC chips, about 66MHz, and running a positively archaic operating system.
  
  I still have the machine, and drag it out from time to time. When this story broke, I pulled it out of storage to test it, and see how it compared. With a 10/100 ethernet card in, running the mac's System 7.5.3, it could successfully play an MP3 while transferring, and it made no difference whatsoever to send or receive speed over the network.
  
  Take note Microsoft: 1994, 66MHz, System 7.5.3, more than 13 fricken years ago.
• To say nothing of traditional multithreading, how do they explain how the entire OS could be run on either of my cores, but just networking and multimedia can't run together on both of them without some kind of tradeoff?
• Interesting, VERY interesting. This either means that Microsoft Programmers are incredibly incompetent or they are hiding something. I can take a really old Linux kernel (or windows 98 install) on a Pentium 233 mmx processor and see less than 0.05% drop in networking performance while playing an mp3. In fact I dont see that drop playing 2 mp3's at the same time while transferring large amounts of data over 100 base T. I do this daily on my whole house mp3 jukebox that is linux based, it has 2 seperate sound cards that plays 2 different mp3 files while I upload another 60-80 mp3 files I corrected the data tags on. I do not see the performance hit of 10% on hardware that is at least 20 to 30 times slower than the typical Vista machine.
  
  What are they hiding?

• Microsoft Windows Vista comes with a new network stack that can adjust or tune itself. On some machines rather than help file transfer speeds it actually slows it down. Many times this issue is caused by third party network drivers.

  Auto tuning can also slow down network browsing of other machines on your network. If you are having local network slowness or file transfer problems try the command below to turn off autotuning.

  You can turn on and off autotuning with a simple command line instruction.

  Run the command at a command prompt (cmd.exe), you may need to run the cmd.exe as an administrator (right click "run as administrator"). Command Prompt by default is located under the Accessories menu folder. If you are logged in as administrator you can simple click "start" then "run" type in: cmd.exe and then run it.

  To turn off AutoTuning

  netsh interface tcp set global autotuninglevel=disabled

  To turn on AutoTuning

  netsh interface tcp set global autotuninglevel=enabled

• The second reason for using a separate process for the audio engine is DRM. The DRM system in Vista requires that the audio samples be processed in a protected process, and (for a number of technical reasons that are too obscure to go into) it's not possible for a svchost hosted service to run in a protected process.
