Speed test demo -see studio for more speed test demos: http://scratch.mit.edu/studios/795672/ ------- This one shows that inserting into a list can be quite slow, and that if you have lots of things to insert, it could well be quicker to actually copy it all into a temporary list, and then rebuild it all from scratch with the extra items, so that you only ever use "add", never "insert" - even if it means you end up adding more than twenty times as many items as you would've inserted!
