There is also a quirk in the DosMerge kernel under Unix 5.3 where a background process called bdflush consumes (at least on my system) 93% of the available CPU time when the machine would be otherwise idle. Running a Dhrystone test here would time slice the CPU but it would still run much slower do to that routine gobbling up the CPU time. -Mike {ihnp4, amdahl, rutgers}!meccts!cimcor!mike
