The pv_ops one may be better or worse under certain loads, but unless we test, how will we know? Once we can demonstrate it, the pv_ops kernel can be improved as needed too. > What I'd like to have is a standardized test with a way of multiple people > uploading it and comparing results so we can run it on as many systems as > possible. > Data correlation could then be done on the data.

As far as I know no one at Clarkson is actively working on it though. I will check with them when I get a chance though. > I'm going to look at the tests you've done as soon as time permits. What we completed were some basic things. There is still more to test. Thanks, Todd -- Todd Deshane http://todddeshane.net http://runningxen.com
