I got 11 ms on my machine:

function getDupesList pList
    repeat for each line L in pList
        if array1[L] is empty then
            put 0 into array1[L]
        else
            put 0 into array2[L]
        end if
    end repeat
    return the keys of array2
end getDupesList

Best,

Mark

Yes, I wish to end up with a list of duplicates, not a list of uniques.

Hi Ian,

I have a couple ideas... Would you be able to upload a sample list
somewhere -- the result of ijwAPLIB_getAllChecksums() -- so we could try it out and measure? Also, just want to double-check that you intend to produce
a list of duplicate items, not a list of uniques.

The problem - trying to find duplicate files in a database (Apple
Aperture), and have found a checksum column for all the image files.

I've had a go at writing a handler to find the dupes and it does OK, but wondered if the bright sparks on the list have any advice on speeding it
up it...
