SUN Ethernet problems

[Cyrus Foughty]

We have a network of 16 SUNs with two servers (3/280's).  We continually
get the error message "NFS server not responding", then after a second the
next  message appears telling us it is now working. Also at certain times
the network just slows down to the point that scrolling in "vi" takes
several seconds. I know the descriptions are pretty ethereal, but any
general tuning tips or ideas would help. BTW, we are running SUNOS 3.5.
