A fairly recent net discussion - in which someone actually (gasp!) posted some figures - suggested that you can cut it down to 5% without any problem. At around 2% the performance started to become seriously worse. Things have changed quite a bit since the 10% figure was originally given - in particular the trade-off between disk i/o and cpu time has changed substantially. -- Richard -- Richard Tobin, HCRC, Edinburgh University R.Tobin@ed.ac.uk "We demand guaranteed rigidly defined areas of doubt and uncertainty" - HHGTTG
