    Our network here has over 50 Suns on it, plus about 10 larger machines.
    The Suns all have local disks for swapping, but load most of their objects
    across the network.

Just an aside (and I have redirected to comp.unix.wizards): if you have a
local swap (hurrah!) on your "diskless", set the sticky bit on the most
frequently invoked or large executables. It depends a bit on which OS you
run, but for most this will keep the image around in the swap partition and
save on repeated fetches from the network.

Now that the kernel automaically deletes images from swap if it needs
swap space, it pays a lot (also to avoid swap space fragmentation) to
sticky executables, and not just if they are very frequently but not
continously invoked. This includes many X applications...
