On the Fujitsu and H-P they were freshly formatted 512 meg partitions (the largest possible under 2.02 due to a bug that has since been fixed). The Quantum and Wren were on freshly formatted partitions of between 70 and 150 meg. I haven't done any empty vs. full comparisons on the A3000. But with an A2000/A2620/Hardframe/Wren III combination I measured about a 50% decrease in speed between a freshly formatted partition, and one about 60-70% full and moderatly fragmented. -- Blaine Gardner @ Evans & Sutherland 580 Arapeen Drive, SLC, Utah 84108 blgardne@javelin.sim.es.com or ...dsd.es.com!javelin!blgardne DoD #0046 My other motorcycle is a Quadracer.
