Use cross reference values for demo-songs that do not halt on a netbook.
On an Acer Aspire One Bk250, 2 songs can give you a direction how much your cpu threshold of your laptop should be scaled to:
The Path 2009 peaks at 71.9%, but does not halt.
Nivi does not halt.
Also read the MSI Wind U100 review where someone did a similar test:

So play those songs and look at the maximum CPU rates of those songs when played on your laptop or PC (turn off multicore usage)… if you can stay under that, your song written on your laptop/pc may as well survive on a netbook.
Also the songs that do not work out can give you indication of what to avoid using or combining.
