Hmm... RH9...
If this was a question about FC2 I would ask
Changed from what OS.
next
What were the previous data rates.

Has the network link to the remote tape changed? After
an update I might expect that routing or driver issues
might be an issue. What network card is being used?
Does traceroute and ping -R return sane results?
next
what does mii-tool return.
next
what previous special tuning was done?
Sounds like an old setup, perhaps someone recalls.
Compression?
next
How much memory is on the box. Perhaps
the new OS is just large enough to push it over an edge.
next
Is this a single rsh connection or is is a sequence of transfers
with the associated authentication, host name lookup overhead etc.
next
What machine rlogins into which machine. i.e. is this a pull or
a push transfer.
next
rsh.... goodness. Pay attention to security and the firewall setup
perhaps this is a ssh link with the associated overhead. Snooping
a handful of network packets might help.
