Real Bad. 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. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Stephan Somogyi MacUserLabs@cup.portal.com NetWorkShop Coord. or MacUser ...{apple|uunet|sun}!cup.portal.com!MacUserLabs Stay alert, trust no-one, keep your laser handy.
