Use 2 GB fragments at the storage units. Then you can check bptm log.
It has all the info you want in kb./sec

Is this linux specific?
I don't have a linux box handy to check, but I'd imagine iostat would do
exactly that.
On solaris, I use iostat with the "-xnp" args and follow it with the
interval time and number of intervals.
For example:
> iostat -xnp 5 100
Gives me 100 shots on 5 second intervals of all the tape devices, read
and write in separate columns, as well as waits, and reads/writes per
second.
