Hi David,
Sun hardware is really not my area of expertise, but I'm sure there are
others on amanda-users who can answer this. If your Sun boxes will only
do 10 Mbps/half-duplex then just make sure your switch ports are set to
either auto/auto or 10/half and you'll be fine.

Here is the version of my Sun OS:
SunOS gitpocs02 5.7 Generic_106541-08 sun4u sparc SUNW,Ultra-5_10
The /dev/hme is FEPS Ethernet Driver v1.115
The host seems too old to support 100/full-duplex.
Do you agree?
Thanks!
David

My tape server is a Linux host (Redhat 7.3).

When I run 'amdump' to backup Linux hosts, the speed is pretty good.

It seems not a network or hardware issue.
Seems? You don't sound particularly sure on this point... In my
experience one thing that is a frequent cause of deadly slow network
backups is a duplex mismatch between a backup client and the ethernet
switch it connects to. I've seen systems that the user had been happily
using without complaint for weeks or months before asking for backups.
When their backup went painfully slow I'd check their network settings
and invariably find a duplex mismatch.
Another cause of slowness can be doing client compression, especially
client best on slow hardware. How old/slow are your Solaris boxen?
