Well, I wrote

1Gb.

I'm using Solaris 8.

The SUM() works as expected now (disks works a lot), but accessing by key
is very cpu-intense and still 0% work on disk.

To sum up: table scans are very disk-intense (which make sense), accessing
by
key leaves disk on idle (I see that it should not work as with a table scan,
but at least a little!)
