Hi thundergnat,

Right, but I am looking for pairs from the 70k array, so that leaves me 70k x 70k / 2 = 2.4 billion pairs, of which I probably only need about 100 million (about 4%) so I really do need to get them randomly.

But you're definitely right that holding the property-lists in memory is the obvious place to start tuning. Just wanted to figure out first if that's truly where the script is spending all its time!
