Mark and Rich,
First off, I misremembered my level 4 results for the FX53 as I posted from home.
SW 2005 (3) .69, .71 s (4) 3.87, 4.03, 4.43 s for three runs. (5) 37.09 s
SW 2004 (3) .64, .81 s (4) 3.43, 3.45 s (5) 33.99 s
I think scatter is normal, especially for the shorter runs. Have a good look at what is running in the background. Virus checker, services, network traffic.
I don't have a virus checker running for this test and I trimmed services per the blackviper list. I am on a network switch so I don't see other network traffic. Even email should be shut down. My task list only has 28 processes running including SW.
I will say it again that the timer times real time, so if some other process grabs a few clock cycles during the test it will show up in the results.
