Hi

I am running a TSM 5.4 Server, trying to backup/restore a NetApp filer
over IP to a native LTO3 tape storage pool. The backups are NDMP images,
with the TOC. The TOC goes to a separate disk storage pool.

I am experiencing terrible performance. In the region of 2 MBs for backup
and 0.2MBs restore!!!

Have checked the basic settings tcpnodelay etc and disk performance etc...

Can anyone think of anything, (sorry, its expansive!!!) Also any real
world experience when it comes to performance? expected throughputs etc
And how to get them!!!
