We are experiencing some quite strange problems with CAP pl196 on
FreeBSD 2.1. CAP is built for native ethertalk. The hardware is a P120
with 64 Megs of RAM, a Adaptec 2940, 8 GB of disk, two 3com 3C509 and
a NE2000 ethernet card (the latter is used for CAP).

Our problem is that copying files _to_ the server from all Macintoshes
but one in our environment is so incredibly slow that speed
practically is zero. Copying a 100K file takes 10 minutes or more.
Copying _from_ the server on the other hand is very speedy. This
problem applies to all of our machines (15 PowerMac 6100, 15 PM 5200
and an old Centris 610). Operating System is System 7.5.1 on the
PoerMacs and 7.1 on the Centris. One of our Macs (a 7100 running Sys
7.5.1) doesn't have the problem at all. All of the machines are
connected to the same physical network with nothing but an 10baseT hub
to separate them from the server.

Fiddeling with aufs' -S and -R parameter setting them both to "1"
caused a disk related kernel panic and a reboot.

We are very puzzled indeed. Anyone got a clue?
