You can now get dynaTrace session traces of your tests run from Dulles (IE7 and IE8). This is exceptionally helpful if you are trying to figure out what is causing the CPU to spike or large gaps in your waterfalls (usually script execution).
To capture a dynaTrace session you need to select one of the “dynaTrace” browsers from the browser dropdown. The session files are linked on the results page (right below the load time for each run) as well as the waterfall page (top-right corner).
You’ll need the 2.0 beta of dynaTrace Ajax Edition to load the trace files.
This is still under fairly heavy development so consider this an initial release and let me know if you see anything acting strangely. Tests will take quite a bit longer because of the overhead in launching dynaTrace so it’s probably worthwhile to only run as many tests as you need (and limit it to first view if you aren’t looking into repeat view issues).
