Yes, this is extremely painful even on my ULTRASPARC 1 running nothing else.
Some very rough performance numbers from my last few compiles follow (19.15b4):

 lines   time (sec)
 ~~~~~   ~~~~~~~~~~
  170     25
  210     30
  287     50
  377     80

Don't know about 19.14 but its definitely way slower than 19.13. 

Two other things I've noticed to be very slow are

  - When M-x find-library needs to build completion table it takes about 10 sec.
    With minibuffer-confirm-incomplete=t, this unfortunately happens even when I
    don't need completion.

  - The presence of even a single new mail message needing to be resplit into
    nnfolders adds about 60 seconds to a normal GNUS startup time of less than
    10 sec.

Haven't had time to look into these yet but figured it was good to throw them
out there in case anyone else has the time.

Greg
