Hi Chris
I see you have 100MB full duplex, but are you sure that your NICs (both in
TSM Server and Exch. server) and the switchports are set to 100 Full Duplex,
and NOT to automatic - in which case it still will use 100MB fd, but at a
terrible efficiancy cost.

Check this and check it again would be my best advice.

Hi all

I've been reading various posts about TDP for Exchange being slow
but I can't believe its supposed to be as slow as I'm seeing.   At the
moment I'm only getting approx 500Kb/sec at a time when no
other backups are running, i.e network and server and doing very little.
I've tried various settings for TDP buffers/buffersize to no avail.

Environment details below.

If anyone has any thoughts on how I can make this perform better I'd
appreciate it.

Thanks

Chris
