That's very good performance, out of curiosity,
is your TSM server also running on top of VM ?
I know VM instances can talk to each other over the memory instead of
over the net

The secret ingredient may lie in the often shunned 'memoryefficient yes' in
the client's dsm.opt.

Ditto.  on one of our bigger file servers, ~1.3million files, 2-cpu
2.4ghz, 2.5GB RAM, SAN attached storage (that gets ~100MB/sec
throughput), it take us 45min to get through a backup.  This seems to be
almost 20X that fast.
