Dave,

Once you have the data going to a file there are a few other knobs you can
turn for performance as well.  One of these is in the configuration file for
the data collection engine you can increase the channel size if your system
has enough physical memory.  The default channel size is 64Mb, I often will
crank this to 128 or higher when I want to get a intensive slice of data.
The immediate beinifit of increasing its size is the response time of the
application under test increases.  This coupled with redirecting data to a
file and incrementally loading it should get you up and running quickly.
