We have an S81 with 10 CPU's. Sometimes when answering the phone
or other distractions arise, I leave a little program running called top.
It shows the top jobs, the load average, etc.

One thing I have noticed is that sometimes top will show that it's
running 30-40% idle even with 200+ people on. Yet the keyboard 
response is slow and clunky. Since the CPU is mostly idle, one must
assume the bottleneck is somewhere between my keyboard and the CPU.
Since it's an ethernet connection, it's nothing to do with a slow
serial port chip or anything like that. Could be DYNIX I suppose.
Probably is come to think of it.
Any ideas?
