 For "comparison" here are my launch times  on a 400/20MB slab; 
When the applications were launched I had the following running: 
Emacs,
Stuart with two shells
Cassandra with the screensaver
Kermit.
After launch all applications remained in place.

Edit 1.2 s

Mathematica  <6 s


WriteNow   <6 s


Improv with API kit < 12 s


Stuart (reopening)  <2 s

and above all  TeX:

hardy{tex/Wavelets}[54>time latex wavelets
This is CTeX, NeXT Version 3.1a

The only objective measurement is the LaTeX time, which is impressive,
while all the other applications (except Mathematica) are open

With mathematica Loaded (but nothing running) the same process took:
Transcript written on wavelets.log.
4.300u 0.516s 0:06.50 74.0% 0+0k 3+6io 0pf+0w

And while mathematica was evaluating a small notebook
4.298u 0.529s 0:15.18 31.6% 0+0k 19+7io 0pf+0w

I don't exactly know what Barry's three times mean; the ones I listed
are until the opened document appears on the screen.

Oh yes -- for what it's worth: vm_stat:
Mach Virtual Memory Statistics: (page size of 8192 bytes)
Pages free:                      146.
Pages active:                    235.
Pages inactive:                 1880.
Pages wired down:                182.

Draw your own conclusions.
