What happens within Microsoft when a Windows Vista or Longhorn Server daily build is ready? Thousands of machines spin up an insane stress test that sucks up all available memory and handles and then pushes the machine to the limits with an intensive set of feature stress routines.

This is an incredibly tough test that helps us find obscure race condition bugs and assess the overall robustness of the operating system.

Join Dr. Sneath and Stress Technical Lead, Eric Hanson, as they expose the great work of the Windows Stress team to the outside world for the first time.

Great interview, very interesting! I am very interested in hearing more about how Windows is tested.

A righteous infliction of retribution manifested by an appropriate agent.
I would like to see the USB test rig or try to make my own! What is the record for the most USB devices connected to a Vista box?

I would say 127 (ie the limit of usb)? I could be wrong.

"I would say 127 (i.e. the limit of usb)? I could be wrong."... I think that is the limit per controller. I think my desktop has a couple of controllers.

And you can always plug in like 6 usb cards into all the nice PCI slots. Thats another 762 usb slots! Wink

Great interview... and oh what I'd give to be able to give that system a spin... if for no other reason then to run seti@home on a thousand PC's at a time.

One wonders if this tool could ever see the light of day for use by non-msft devs on slightly smaller projects.

Also before I forget... Go (home) Saints!

Uh,.. uh..  I think Eric Hanson was "Stressed" by having the video camera in front of him.

But good topic...

 Automated stress testing of Office apps would be interesting to learn about like Word, Excel and Visual Studio, etc.


Charles,

You need to work on your camera moves.  Slow down.  You fly left to right and up and down.  Just giving constructive criticism.
