Ahh, so this is a fresh install.

        The suggestions about checking out the NIC and switch
configurations are a good. 

        I suggest doing an FTP between the 2 hosts to see if your issues
are at the OS or TSM level. If your FTP is about as slow as TSM backups,
then it is likely that your network devices are not agreeing on the
negotiation speeds, and might have ended up in half duplex.

        The "entstat" command is helpful in seeing what the card is set
to and what speed it's actually working at.

It was a kind of mixed i think (not very small files any way - exe & big
DB files), anyway ...for a single file 300MB it took 30 seconds. it
seems a poor performance to me. The OS is in the state it came
preinstalled , no patch added (right now i cannot look for the ML), no
params changed . Same to TSM ...only installed on TSM I hope u can
recommend some patches or tuning for parameters (in OS or in
TSM) in order to improve the performances.
Thanks ,
Madalina
