Sean Owen commented on MAHOUT-916:
----------------------------------
This makes the tests much slower for me, since on my laptop the several
threads' I/O is just contending for the disk head and at 20% CPU only. It also
makes my laptop unusable. I'd suggest 1 thread per core at most -- or maybe cap
at 2-3 threads.
