TSM client 5.2.2.0 on a Solaris 7 server, gigabit fibre Ethernet adapter.
TSM Server 5.2.2.1 on AIX 5.2 p630 with fibre gigabit Ethernet. Different
VLAN.

During the backup of this client (actually 4 out of 11 Solaris clients) the
backup just drags along. Looking at the sessions on the server we see the
session in RecvW state, but the wait time just goes up and up..sometimes in
the double-digits before more data goes in.

Doing a large FTP to that server (130MB) took just a few seconds. The other
7 Solaris clients, same TSM client, same OS level, backup like you would
expect over gbit.

According to the switch, the ports which are configured for autonegotiate,
are at full speed and duplex.

Anyone got ideas? Searching the archive brings hits on 10/100 ethernet
adapters not being set correctly.
