I've found that that question makes the difference between using 6% & 12% ... 
particularly large data transformations ... but not higher than that.  And 
I've had ample opportunity to test on 2 reporting servers.    For one thing, 
with very large reports one tends to have a lot of I/O binding, which is 
handled by the kernel.
