If you are not willing to run asun's appleshareip implementation with
netatalk, it is a complete waste to upgrade to 100Mbit. However, you
do gain some performance, from about 500K/sec to 900K/sec in my case.

If you use the netatalk+asun version of netatalk, you can get an
incredible performance boost. I've made the following table, all based
on files copied from a server with P150, netatalk+asun17, 3com 3c595
Vortex, and with only one single client connected at each time. I used
a lantest program to check the speed. (I don't remember which one)

Client NIC
PMac 9600/200MP AsanteFast 100Mbit 3300K/sec
PMac 8500/150 Dayna Bluestreak 100Mbit 2500K/sec
PMac 7500/120 Dayna Bluestreak 100Mbit 2400K/sec
PMac 6600/66 Farallon 100Mbit (Nubus) 1300K/sec
PMac 6100/60 Farallon 100Mbit (Nubus) 900K/sec

The hub used between all of the above is a 3com 100Mbit 12 port.

These speeds are the actual speeds i get when i copy files to/from the
server too.
