Flew from Logan ('tho to DFW) last week on Friday at 9:25 AM. Using FC check-in, total time from cab to past the new enhanced camo-clad security was 8 minutes, leaving me an hour and a half to read before boarding.
DFW was much the same - arriving at 9 for the 10:45 got me on the 9:30 coming home.
Of course, the day I'm late will be the day the lines are long...
