	    I have heard second hand that performance of symbolics machines
	    (certainly this was about L machines, maybe G's too, that is part of the
	    question) "degrades" with more than 9 MW of memory. Anybody know
	    anything about this? I have no other info

	Back in about 1986, a bug was discovered in the virtual memory system
	that caused performance to degrade in machines with tons of memory.
	It was fixed the same afternoon.  I know of no such problem any more,
	but the story of that ancient bug is sometimes told for its amusement
	value.  We have some substantially loaded machines in-house that have
	the expected performance: fast.

    How loaded is loaded?
    What are the limits?

I dunno, something like 14.5MW on a G-machine (3620, 3650).
L-machines are smaller.
I-machines are bigger.
