Тихий Ужас

Вот такой вот он www.microsoft.com (более детальные подробности по ссылке):

One of our more challenging systems from a server subsystem utilization perspective is www.microsoft.com. The site handles 15,000 requests per second, 1.2 billion page views per month, and 280M worldwide unique users per month as well as supporting ~5000 content contributors from within the company. This site has close to 300GB of content consisting of some seven million individual files on each server. Due to this scale and the variety of applications hosted, the site heavily exercises all of the major subsystems - memory, CPU, network, and file I/O – on each server.
