We have an Ethernet set-up, based primarily on Mac II & SE/30 computers.
The servers are a II & an SE/30, and most workstations are IIs.  We have
realized a dramatic speed-up in throughput by switching to Ethernet.  I
consider the cost & set-up effort to be worthwhile.

As for the reports of little or no speed-up from LocalTalk to EtherTalk, all
I can say is that you CAN realize substantial improvements in file & data
transfers by upgrading.  File transfers show quadrupled throughput (from 16k/sec
to about 65-70 K/sec.) with a II workstation, doubled speed for plain SEs.

I don't quite know how a Plus was hooked up to Ethernet, but the SCSI-based
connections reportedly suffer from very poor performance.  That could account
for the minor speed improvements being touted.

Again, Mac II level & up workstations doing work w/ high net traffic will
show dramatic improvements switching from LocalTalk to Ethernet.
