It looks like the NIC settings arent 100/full duplex om both systems and
switch.
How did you calculate 5,84GB/Hour => 13,3 Mb/sec ?
If you do it backwards 13,3 MB/s * 60sec * 60min=47,88GB/h.

Please respond to
"ADSM: Dist Stor
Manager"
I am quite disappointed by the TSM software performance.
Let's take :
WIN2000 client, Bi-Pro, nothing running on the machine except TSM client
WIN2000 server, Bi-Pro, nothing running on the machine except TSM Server
Client is backing up to server, using 100Mb TCP/IP => Throughput of
5,84GB/Hour => 13,3 Mb/sec !!!
With LAN-Free, result are the same !!!
So, having machines with CPU used with less than 10%, LAN card used at 10%,
where is the bottleneck ?
Backing up to disk or to LTO tapes does not help increasing the
performance.
Following parameters are set :
TCPBUFFSIZE=128
TCPWINDOWSIZE=63
TCPNODELAY=YES (AND TESTED WITH NO)
LARGECOMMBUFFERS=YES (AND TESTED WITH NO)
I was hoping to reach at least 25GB/Hours via a TCP/IP 100Mb network and
50GB/Hours via LAN-Free to LAN device
Many thanks in advance for any feddback
