Interesting. What exact code did you use? Here's mine:
on mouseUp
repeat 1000000
put random(1000000000),"" after L
end repeat
put the long seconds into T
get greatestLessThanSort(L,500000000)
put "sort" && (the long seconds - T) && it into fld 3
put the long seconds into T
get greatestLessThanRepeat(L,500000000)
put cr & "repeat" && (the long seconds - T) && it after fld 3
end mouseUp
function greatestLessThanSort pList,V
sort items of pList descending numeric
sort items of pList by each >= V
return item 1 of pList
end greatestLessThanSort
function greatestLessThanRepeat pList,V
put empty into R
repeat for each item i in pList
if i < V and i > R then put i into R
end repeat
return R
end greatestLessThanRepeat
And the results:
sort 0.916539 499999879
repeat 0.331764 499999879
