So I assume. If I were to work harder at it, I'd ensure that I only attach 
the swap partitions that are not on the same physical disks as the main 
file-system (which uses md0 to md6 on two SATA disks). I may do that 
sometime, but I don't imagine I'd see much benefit from it in practice as I 
read that the kernel is pretty efficient at sorting this sort of thing out 
anyway. Or I could just juggle the priorities so that the swap partitions 
were used in the most efficient order.

I can only repeat what I said, that I don't notice any slowing of HCI 
reactions, and that the huge compilation seems quick enough too.

Accept no substitutes! There again, I think disk capacities are just 
excessive nowadays; they just encourage laziness in management of the 
resources. A couple of 60GB disk would be plenty for me, with backups to a 
USB disk which I can connect to any machine.
