A quick run here on a full firenet feed with weather alerts turned
on gives me the below.  I only included the top partof the listing,
down to 0.5% CPU usage.  There are plenty more below that, but of
course the heavy-hitters are at the top.  The numbers settle down
more with longer runtimes, but this should give a quick idea as to
what to look at first.  It appears to me that weather alerts are
causing some slowdowns 'cuz we have a number of alerts coming across
right now.  The next heavy-hitter would would be the dbfawk stuff.

Note that I wasn't doing any map operations other than the weather
alerts for this run.
