Memories, memories. 60 users on an 11/70 with 640kb of core. Times were tough then... < I wonder how a load average of 50 on an 11/70 compares with a load < average of 128 on an 11/780....... Load averages seem to be pretty much an absolute, regardless of the hardware. Anyway, an 11/70 was faster than a 780. Who would bother with a machine like that. So here's the plug: the nice thing about machines like our Sequent is that you get to divide the load average by the number of processors. To get a load average of 128 you'd need 700 processes on the run queue (6 CPUs). Given that we only have table space for 245 processes, we can never see a load average greater than 40.
