- Once Keith calms down enough so the foam from his mouth stops getting
- all over his keyboard, perhaps he'll come back and give you a real
- answer. In the mean time, here's the gist of what he'll say:
-
- The Sparc tells NetWare NFS that it's ready to receive a certain
- amount of data. NFS has no mechanism for moderating data rate: the
- server is free to return the requested data as fast as possible.
- Unfortunately, NetWare NFS's "as fast as possible" is too fast for the
- Sparc to handle. This isn't entirely uncommon in the NFS world. In
- fact, NetWare NFS itself can have a similar problem if it's crippled
- with a sufficiently slow network interface card.
-
- I'm not really an expert on NFS, so i hope i've managed to clear this
- up a little without mangling the facts too badly. And i actually
- don't know the first thing about a "Sparc IPC", whatever that is, i'm
- just extrapolating from Keith's comment about it, based on my limited
- knowledge of NFS.
