MORE RAM!
It is a complex shuffling dance between the file system, the CPU RAM, the ND
RAM, and the various swapping and backing algorithms (and their use of the file
system, ...). The more time it spends in the dance, the less useful stuff from
a user point of view. 16 MB of CPU RAM is not enough. If you are doing a lot of
image display, 16 MB of ND RAM may not be enough.
The ND has turned out difficult to tune and make go fast --- from a couple of
years dinking with them and asking NeXT engineers lots of questions. The only
practical solution we have ever found is
MORE RAM!
