has been no doubt about the reduced level of network performance
experienced compared to Windows XP. However, some users over at the
2CPU forums have discovered an unexplained connection with audio
playback resulting in a cap at approximately 5%-10% of total network
throughput. Whenever any audio is being sent to a sound card (even,
several users report, while paused), network performance is instantly
reduced. As soon as the audio is stopped, the throughput begins to
climb to its expected speed. It's a tough one for users -- what do you
pick, sound or speed? So much for multi-tasking."
