today I have the same issue on a simple P4 processor
the problem appear when I aggregate data based on a virtual dimension.
my cube is simple (1 millions of rows), and a bigger one (20 millions of
rows) takes less time on the same computer.

its a random problem related to specific aggregations, because the same cube
with less agregations works fine.

Try to process your dimensions (full rebuild) before processing your cubes.
Hope this helps.
