It is unclear whether you have all these 50 Macs on the same LocalTalk
net, or whether they're subdivided with routers between them.

If they're all on the same net with only a single way of getting at
the Sun, I'm not surprised in the least that your performance is
non-existant.

LocalTalk was not designed for this kind of load. Splitting a LT net
into zones with one server per zone will make LT *much* nicer.

Most of the time, when people complain about LT being too slow, it's
beacuse their net isn't designed well. LT is quite forgiving with a
low node count, but the more nodes you have, the more thought you have
to put into net design.
