I don't really understand what you mean. You need to be more

Hmm, which of the following is the fastest?
random number from 1 to 6
some word of "1 2 3 4 5 6"
some item of {1,2,3,4,5,6}
Some item is by far the fastest.
But none of these are nearly as fast as writing your own random
number generator in applescript. :)
I developed an applemod called pseudoRand to do this because I was
running monte carlo sims that needed millions of trials and I wanted
them to finish in an hour or two instead of weeks.
Whatever happened to applemods anyway? The link has been saying
"under construction for a year or more. Is it dead? Is that a sign
of general bad things at macscripter.net?
Anyway, if anyone who didn't download back when applemods was working
would like it, I could send out the script to them (or to the list if
there is a lot of interest).
The disadvantage, of course is that you have to include a few dozen
lines of code or so, but it's very fast.
Ticks results from grabbing 100,000 each of RandomReal (a floating
point number between zero and 1), RandomInt (an integer between 1 and
applescript integer limit) and Random(a,b) (an integer between a and
b inclusive) are in the following list: --> {189, 172, 982}
So for the common case, you get roughly 6,000 numbers per second on
my G4/450. I'm on OS 9, where nothing else works even *close* to
that fast. Looking at Emmanuel's numbers, I suspect that osaxen have
been speeded up some in X.
The "some item" and "some word" calls vary in speed depending on the
size of the list/string, which my Random(a,b) does not (whatever
range you choose, it takes approximately the same time to generate a
number).
