I think I already provided some data that showed where the problem
is.  It has to do with the large number of weather alerts we get
during the storm season.

Sorry that you can't get the profiling working.  With a bit of luck
you might get that working yet.

I plan to look at this problem soon if someone else doesn't beat me
to it.

No, it's problems with lots of weather alerts.  The algorithm for
comparing new packets with old weather alerts is inefficient.  Try
connecting up to a filtered port and skip the weather alerts.  You
should see few slowdowns that way.
