here at nstar, we are running with BUSSON of 9, BUSSOFF of 4 and DMASPEED
of 6.7mhz (using a 1542B, BUSS running at 12.5mhz) and have seen some 
drastic improvements in throughput over that of the default configuration.

Our drives are CDC Wrens IV's - and I assume the the default is that the
cache is enabled on the drives -
