Optimizing scripts in LC is not the same as running reports in other
software suites. If you only need 10 results, you probably don't want to
handle all items twice.
I hate to loop through all items even once. But if I do, I may be done!
I'm not making a full report to print out; I'm just getting my 10 items.
If I use sort or filter, likewise, I will do whatever necessary to keep
it short and sweet, even if that means adjusting some of the starting
If the sort really is taking more time than the loop, something is
bogging it down. Look at the random() and arithmetic attached to the
sort. That's potentially like running a whole lot of LCS. So if you
sort, try a plain numeric sort with no fancy stuff added. Then go grab
your 10 - the other requirements can be addressed before or after the sort.
