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?
