Bad idea (thought not nearly as bad as on a Windows machine).

As speed doesn't seem to be a matter for you, trying to lower the number 
of competing threads using +WT4 or some such could be worth trying. With 
the swap drive surely being the bottleneck, you might even consider 
+WT1, reducing page thrashing to the absolute minimum possible in this 
setup.

Note that the more worker threads you have, the less coherent 
consecutive memory accesses will be.
