Hello, I have an issue with some Sun boxes. Backup works fine (I am able to
overload the Network 100Mb/s). But the restore troughput seems to be limited
to 10Mb/s. Network config seems good I able to do FTP between the box with
good transfert rate. Tests are made with 256MB files size and disk stgpool.
Backup and restore works fine on Windows Client !

Network is 100Mb/s Switched and 1Gb/s Fiber for TSM Server
No compression is used for those boxe.

Here is my config :
Server : TSM 4.1.3.0 on Win2K SP1 ADV on HP 8xPIII 700Mhz, 4GB Ram  attached
to STKL700 ... 
E450 Client : TSM 4.2.0, Sol8, 4xCPU, 2GB Ram
E5000 Client : TSM 4.1.2, Sol7, 8xCPU, 8GB Ram.

Does anyone have an idea ?


Here is an extract of trace for the backup and the restore of the 256MB file
size.
